Coding Interviews Be Like

Coding interviews are hard. But why grind LeetCode, study data structures and algorithms, and read Cracking the Coding Interview when you can simply "throw a hashmap at the problem"?

The code looks like Java, do the questions in your area for Java Developers really look like this? Im from Poland, but I often aslo apply to international companies, and those mathematical problem solving seems a thing of the past here , assuming we are talkign about bussiness software. 10 years ago it could happen (i remember when Codility was very popular here, many problems were a variation on quicksort...) , but nowadays its usually just a lot of knowledge checking : some basic Java questions,.Java 8 constructs alwys, design patters, frameworks (Spring , hibernate etc.), webservices,SQL and no SQLdb , javascript, coding theory SOLID etc. , maybe they give you some code to review. I actually think its a better approach because that relates much more to what you will do at work with bussiness software. Unless you apply for games software or some niche science projects, I guess, but its rare with Java.

i think interviewing candidate just based on algorithm solving is just stupid. In work 90% of employees will never encounter this. And things you want to test are untouched.

[@Mothuzad]

@@opatechnus That's a strange reply to the root comment. Anyway, if it's a good interview, the algorithm skills aren't meant to be a reflection of practical work, but rather, it demonstrates fundamental skills that are required to do good programming in general. A typical coder shouldn't spend much time optimizing, but they should at least not write code that's absurdly inefficient, and avoiding those pitfalls should be so natural that there's never even a conversation about it. That's why these kinds of technical questions are seen as a bare minimum for hiring.

I'm a german software engineer working at a big company developing MASSIVE software (over 80 million lines of code) and i've never had a "coding interview" lol. Also i think that understanding problems quickly and knowing where to find the information you need is a far more important skill than explaining a sorting algorithm when you've done nothing else but learning them for the last couple of days. When you work and don't refesh your sorting algorithm knowledge you forget 95% of it after a few weeks anyways and even then you can just google it. Not something to differentiate good coders from bad coders imo. Using the best optimal runtime algorithms possible is pretty important but as i said.. you can just google it, it's just important to have heard it once and to know that it is a thing.

[@shaunreich]

The funny part is, for 90% of the use cases, you're doing it wrong. It's the same thing with security, don't reinvent the wheel, your wheel won't be as round, the stdlib of any language you're using has a much better sorting algorithm than you will be able to make (they actually use a combination and heuristics and can even run in parallel)

[@jeromesimms]

@@josephubi9096 Hey, sure. It really depends on where you're at currently and what you are trying to do within the field of computer science; whether it is web development, game development, data science And AI, or becoming a back end web developer. However regardless of what you want to do, having a good foundation is very important. So I'm order to learn the basics of how to program I would recommend learning python as it's quite beginner friendly, although personally my first programming language was C and looking back it was definitely a great foundation but extremely hard to pick up at first. So in order to learn the basics of programming with python I would recommend the course Python for Everybody (you can find it on Coursera, edX and even KZbin) because it will start off slowly introducing you to simple topics but by the end of it you will know how to use python to parse a web page and make requests to an external API. After you learn the basics of programming with python, I think you should switch gears and learn a bit of web development by learning html, css, and JavaScript. A good resource for that is freecodecamp.org or even the Odin project which you can find online. Once you do that you should have a good feel for the basics of programming. Reading computer science textbooks can also help too and then you can decide what you would like to build next. I hope this helps you. In fact, here is a link to a GitHub repository that gives an alternative line of courses for you to take: github.com/ossu/computer-science

The main thing to take away from these interviews is that you will always be questioned on your solution to the problem. Invariably you will be able to improve it to some degree, the interviewer just wants to see if you know how. From my experience when I didn't know something it wasn't a bad thing, it was just a way to find the extent of my knowledge. I got good feedback about my solution after the interview and got the job. So when you are in this situation be calm, do the best you can and if you don't know something then don't worry about it, worst case scenario is you don't get the job and you never see that interviewer again.

I am strongly against high pressure coding interviews because you end up losing a lot of good talent and personalities just because they couldn't come up with a solution on the fly in 10 minutes. I look for people who are excited to learn and passionate about their field. The rest will fall into place from there.

[@BeefIngot]

Same here my dude. A lot of people need to realize that this type of efficiency isn't often necessary and when it is you'll get a lot of time to make sure the real solution is decently planned out. That should give some comfort to people who feel like their hopes are dashed. There are plenty of business goals where the main goal is simply automating the task because for that application, computer time is cheap.

[@gabrielredmund9994]

Generally not what they are asking during the coding portions of interviews. I was going for one job, a Ruby on Rails job with... I can't remember what they were doing, but it wasn't anything new or revolutionary. First interview went great and so it was on to the "coding challenge" which "will not be an arbitrary algorithm challenge." The challenge? Rotate a matrix 90 degrees counter-clockwise. Rails devs do not rotate matrices. They do not deal with binary trees. They do not build a brand new Set class. We have the stdlib and other gems for things like that. For some reason, though, the whole "here, have an obscenely complex code challenge that has nothing to do with your job, nor will you ever have to do anything remotely like it" coding challenge is the "in thing."

[@silverstorm06]

That's comforting. I'm pretty sure I just failed an interview where they asked more complex questions than this.

Probably one of the most important basic CS classes is Data Structures-definitely worth reading a textbook if you're self-taught. At the end of the day, I'm glad I chose to go back to school to study Computer Science (I never would have taught myself Calculus or Linear Algebra-and the structure has been good for pushing me to learn).

you can do something like for i in range(len(arr)): if mp.contains(target-arr[i]): return (i, mp[target-arr [i]) mp[arr[i]]=i (no need to store both the 2s, when you find the second one you return)
