This was a very accurate portrayal of a typical interview for a mechanical engineering position at a large tech company. The steel aluminum question is a classic. Love how you inadvertently said hit me😂

[@TamerShaheen]

Yea haha...I’ve done enough interviews to notice these patterns

[@noonenoesbutme]

Mechanical Design Engineer here. I did 3 interviews (2019). 267 applicants, 20 went to phone interview (just voice), 10 went to 1st in person interview with prospective manager and 2 other engineer managers, 5 went to final interview with the director, future manager, and 1 other lead engineer. I beat them all 😎. The director and other engineer were gauging my personality and ability to work cross discipline and culture fit. This time my future manager gave me technical questions like this video, I used a white board to initially problem solve for 5-10min before presenting a final answer. THEY DON'T CARE IF YOU GET THE RIGHT ANSWER. They want to see how you THINK how you PROBLEM SOLVE. That's what an engineer is, a problem solver. Beat all 267 applicants, out of college starting at $84k (Sacramento, CA). His reactions to feeling like he killed a question and then being surprised by another is SPOT ON. Side note: if asked a technical question requiring a formula you haven't memorized, be honest and ask for the formula they WILL give it to you. Also, always have ready "So what questions do you have?" questions. I go for "What's your favorite part of working for XXXX?" Or "What fundamentals of engineering do you most commonly finding yourself looking up during a design phase?" Or "What's the most difficult engineering problem you've faced workjng for XXXX?". I find these questions throw off the interviewer in a good way. It makes them think the way they made you think and is the cherry on top to making a memorable impression. Go out there and GET PAID.

Accurate 100%. I hate interviews so much. Feels like you take 10 exams at once and then you find out that you have to take them again 2-3 time more. In real life, no one would expect you to respond to questions or solve 10 problems in one hour. When you work on a project, you have weeks or months. It would be better if the first interview would be just getting to know you and for the second they would just invite you over to their place and let you work there for a day. They can see what you're like, better that way.

[@MarkSmith-vo1vn]

@@TamerShaheen Quick Question: For the rod sliding down the hill, I got the right answer but did it differently. Since the moment of inertia is mr^2. The solid disk has smaller r values for different point masses. Therefore the moment of inertia would be smaller, compared to the hollow rod. Since moment of inertia is small for the solid cylinder, their would be more angular acceleration of the solid clinder, which of course results in a higher angular velocity. Since the rotational kinetic energy is proportional to angular velocity squared, it would have less tangential velocity. Therefore the hollow disk would arrive faster. However, apparently this is wrong. So I wonder where my thinking is bad.

[@LiveType]

@@MarkSmith-vo1vn Is it sliding or rolling? Two different problems at play with different mechanics to take into consideration. For a sliding rod: with similar friction properties and no air resistance the answer should be arrive at the same time regardless of mass. With air resistance, if the aerodynamic properties are similar the one with more mass would be slowed down proportionally less as the force from air resistance should be the same for both and thus arrive slightly faster than the one with less mass. If they are rolling: the one with a lower moment of inertia (solid rod) would arrive faster than the hollow rod due to the equation showed in the video. IE hollow objects have a higher moments of inertia than solid objects. Look at an equation for moment of inertia. Basically the farther away the mass is from the center of rotation, the higher the moment of inertia. Thus a sphere has the lowest moment of inertia by solid objects for rolling with a solid cylinder in second place.

[@luis199818]

Nice video! In the question about a solid and hollow rods sliding, I think the right answer would be that the solid one reaches the ground faster due to it having lower moment of inertia, so less resistance to roll (hollow is always slower). Both have the same energy=mgh, but when sliding the one with higher inertia will have less translational velocity. I'm not 100% sure though.

Really great video. I've done probably a dozen interviews in my career (I got an offer more than half of the time) and I got asked technical questions like the examples pretty infrequently actually. I kind of wish I actually got asked those more often because then I could show off what I know. Although when I've been on the other side of the table I've been a bit reluctant to ask those because I rely on search engines and computer programs so often myself I don't find it fair to ask questions like that unless the person has a computer. Honestly the next time I need to interview someone I'll think about giving them a laptop if it's an in person interview and asking them some easy questions or telling them it's ok to use Google or other programs if it is a video call just to make sure they can do this sort of work.

I have had dozens of engineering interviews and I have never been asked any of those kinds of generic questions. I don't know if this is specific to the industry I am in or maybe geographically specific, but every question I have been asked was very focused on the type of product I would have been dealing with. Most of the interviews I have had were in aerospace engineering, more specifically for mechanical design positions, repair analysis positions and manufacturing analysis positions. The typical question would be to receive drawings and determine the type of manufacturing, the function of parts, to find features on a drawing and describe them, etc. There is also a general emphasis on projects done (this is the moment to shine with extracurricular activities boys and girls). Depending on the industry, there may be generic questions about the fundamentals of the products too. For instance, a typical question from a turbine engine manufacturer would be to describe the engine cycle or to determine what type of turbine engine you are looking at (given a drawing of some sort). Long story short, be prepared for the specific details of what you are applying for. Also come prepared with decent past projects to showcase your skills, they can make or break an interview a solid 90% of the time.

As someone who just got a graduate role in a large engineering company, I would say that anything outside your bachelors like, internships, Research roles, Master's degrees and personal projects are critical for reducing the amount of failed interviews you go on.

[@masterdementer]

I'm not chemical engineer but think it should be the one with larger diameter. Just cuz the rate of flow remains the same there will be significantly more pressure in the smaller pipe than in the larger diameter one.

[@jackkohlsaat6643]

As far as I can tell the larger pipe will have lower pressure drop since the diameter is larger causing less of the fluid to be in contact with the wall and the velocity is lower causing the frictional factor to be lower. This leads to less overall frictional head loss

[@adamblomberg]

I'm no engineer but I'll try answer the question. Assuming the pipe contains a homogeneous fluid, not something like air on top of water flowing in a sewer pipe. Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure. Think of a convergent pipe (decreasing diameter) the velocity of the fluid increases as the pressure decreases. In a divergent pipe (increasing diameter) the opposite occurs velocity decreasing as the pressure increases. However there's a catch. In a rocket engine hot gases are expelled from the combustion chamber out through the nozzle. Notice that from the combustion chamber and out it takes the form of a convergent diverging expansion section. Contrary to what you might expect when when high pressure fluid travels through the throat (smallest diameter of the nozzle) and into the expansion section the velocity will dramatically increase to supersonic speed while the potential energy of the pressure decrease and it's converted into higher velocity.

[@NoanatorTV]

Im sorry i hope you dont take this the wrong way but i have a few suggestions. First i have to assume you ment rolling down the ramp not sliding, as you answerd the second part of the first question as if the rods were rolling. 1.Question part1: Same mass at same outer diameter (if implied) means the hollow rod must have a higher polar moment of inertia. same mass also means the same gravitational force accelerates the to masses. thus the solid rod experiences higher angular acceleration. when it comes to air resistance you are also sadly false. the projected frontal area is equal for both rods. but the hollow rod wil most likely create larger "wingtip" (yes even tho its not a wing) vortices due to the cavity wich induces additional drag. final answer: solid rod. for the case that you actually ment sliding, regarding air resistance, solid rod would still be the correct answer (making these statements about fluid dynamics witch these relatively complex cases is dangerous to begin with tho) 1.Question part2: your solution sadly doesnt add up. same volume at different mass implies different gravitational force, so torque wont be constant. your solution treats torque as constant. same volume additionally inferres that the hollow rod must have a greater outer diameter (torque cant be determined). if the mass is different (at same volume) then the density of the rod's material must be different. therefor this question cant be answerd without information of mass/density, as isformation on gravitational force is needed. 2.Question part1: correct but you should work on your terminology. flexibility->stiffness, or just state the "e modulus". also the call that steel is "harder" is not neccesarily correct (hopefully you actually ment hardness and not strength but i belive so) hardened aluminium can be harder than unhardened steel (135 HB vs 120 HB, HB= Brinell Hardness) 2.Question part2: the stress strain curves were correct even tho you should have included a holding point at the yield strength, wich is characteristic for non treated metals. 3.Question: creative answer, tho potentially prone to cause physical harm.

What you mean has to be the moment of inertia then you are right and the hollow rod has a higher moment of inertia and in fact has a slower angular acceleration. I assume the air resistance is negletable in this case at such low speeds.

@@florianhinsch4912 you are right i mixed up the terminology. I ment the mass moment of inertia. But ultimately we come to the same conclusion.

[@florianhinsch4912]

@@NoanatorTV i have to admit that i only read until i saw that and thought your thought process was wrong. the other answers seem plausible

[@ITHowToAsap]

Recommendation: Instead of asking for a few minutes to think about it, think out loud! interviewers are looking more for the thought process than getting the correct answer back.

[@Arannatt]

I don't know shit about engineering, but i'm taking the ielts test soon and your professional range of vocabulary helps a lot.

learning and development!!!

Hey, really nice video and the others too! I was wondering if they actually ask those kind of questions about materials and the other calculation questions in job interviews. It seems really close to the material you study in the mechanicale engineering courses.

[@TamerShaheen]

It depends on the interviewer. Some will only ask u about ur projects, while others will ask u calculation questions and stuff similar to the work u did in school.

[@JB-dv7ew]

I did 2 internships and have had 1 full-time job as a mechanical and probably have done 6 interviews total. Only 1 asked me technical questions, the rest where just about what I liked to do and my projects. This is just anecdotal obviously.

[@yousafhassan4588]

Bro need a video specifically on *mechanical design* some tips and ur experience so far in the industry.

[@TamerShaheen]

Ok for sure

[@grayz8834]

damn I would be stuttering in most of these questions lol

[@douggale5962]

This is the way it is in all highly technical jobs. They get so many unqualified people applying dishonestly, they put each candidate through a gauntlet. What you showed used to be the "phone interview" phase, where they eliminate people that aren't even close to qualified. The interview with several people will have each of them evaluating a particular aspect of your skills, with at least one of them evaluating your interpersonal skills, usually a human resources person. There will probably be four other candidates, you all rotate through the interviewers.

[@MisterBinx]

This video makes me really nervous. I'm close to graduating. I'm breezing through my senor year and feel like I don't know anything. I actually was able to answer all the questions you used in this but still feel like in a interview my questions will be something I really don't understand that well.

[@shikasmat]

the fuck I usually forget everything after an exam

[@mohdadilkhan4568]

so true brother i recently given 3 technical interviews and i i can feel that....

[@ronnydragon2211]

As an aspiring engineer still in high school I feel intimidated xD

[@AhmadAlZA]

I love this!

[@itsJoonsung]

I have interviews coming up and i'm stressed cause I don't know how to study and prepare for technical engineering questions

[@renruiliu7233]

From the HR's view, is that ok for the candidates to use google or other tools during the interviews?

[@TeganBurns]

I despise the "We'll reach out to you" line. I always follow up with "when can I expect to hear back".

[@abdulhakimal-zekri6148]

Tamer you are the best thank u very much

[@jvg7806]

at 5:15 , T~ G ~ m (G being weigth, m being mass), so the density shouldnt effect your theoretical speed. However ofcourse the denser one would percentagewise be less effected by the air resistance, right? Without air resistance the densite shouldn't matter
