Top 13 Automation Engineer Interview Questions & Answers (Part 2 of 2)

[@olyanamilyen]

Yes, kind of accurate. 2 months ago I had a 1 hour 'long' interview at a multinational company and for me the questions were the following (I will list any, including the ones in the video): 1. What kind of industrial communication protocols do you know? Tell me something about them. (ModbusTCP/RTU,PROFINET,PROFIBUS,etc.) 2. What is the difference between PROFIBUS/PROFINET? What component is needed to PROFIBUS, how and why we use it? (resistor at the end of the bus) 3. What are a 5 PLC languages widely used? (IEC standard) 4. Write an easy PLC program in the language you prefer. (I dont remember correctly but they tested if I could use S,R,Timer,NO input,NC input, Relay output,positive and negative edge detection correctly.) 5. Tell me about the OB blocks of a PLC (OB1, OB100,..) 6. There is a sensor, you could use voltage or currect signal, what would you prefer and why? 7. Difference between 0-20 and 4-20 mA. 8. Widely known PLC manufacturers

[@vishnukr8010]

Can u plz share me the answer of 6 th qsn exactly

[@oscarwilliams2316]

i assume this was for an advanced apprentice or job interview, not a level 3 interview? thanks

[@NiravVihaan]

@@vishnukr8010 Current signal is more preferred over Voltage because Voltage will be lost over increased distance which is not the case for current.

[@ORIGINALCRESTED]

I really appreciate the steady volume and calm, clear voice in this video. Thank you for the information. I will listen to this several times while driving a tractor trailer vehicle carrying cargo across the nation. 🚛

[@realpars]

You're very welcome!

[@Greynelson]

When my work (a manufacturing site) held interviews looking for a Automation Project Manager, I was amazed that none of the interviewees could not answer basic questions like: "give me an example of a project that you lead to implement a PLC control system?", "when working in a blue chip team how would you influence others to make your project their focus to achieve your goals?". The interviewees were more interested in being technical about signals and coding, rather than basic team skills.

[@Sundareswara_Nathan]

You referred "Signals and coding" here... Will you explain little bit more about it. I am seeking for APM post. It may be much helpful to me in my preparation, sir.

[@Guitarplayer724]

I've dabbled in automation for years as a maintenance technician, but that first question would of sunk me right off the bat! :D

[@alexanderb.7899]

Same here. Senior Automation Engineer in control programming, 17 years of experience. If they would ask me that during the interview I would tell them to go see Wikipedia. :)

[@NathanKabler]

i know 4 of the 5 🤣

[@houston-wk1md]

I've recently taken the past 6 months to learn controls and automation, and I'll start applying here shortly. Thanks for the possible questions!

[@realpars]

Great job! You're very welcome, and best of luck with applying!

[@Jarito1903]

[@Danyl96]

Thanks for your video! I'm Lead Automation Control Engineer from Ukraine. My experience shows that in Ukraine most popular PLC are Siemens, Schneider Electricctric and Mitsubishi. I/O module are Siemens, Schneider Electric, Phoenix Contact and few WAGO). SCADA are WinCC, Citect SCADA ,Wonderware and Trace Mode.

[@andrewfurtado4875]

I’m beyond nervous, I’ve worked in food processing plants for 2 years and am very familiar with SCADA interfaces and sensors, etc… but never have had a maintenance position besides doing HVAC since i was 16 with my father… i somehow got a callback for interview for tomorrow, I’m so nervous, I’m a nerd with electronics and love working with my hands so it’s a mix of both my dream jobs, programming and maintenance… i really hope i nail this interview. If i don’t, I’m gonna continue to study and do research to eventually get my career.

Hi realpars.. I want to ask because I'm still a beginner, how is the principle that the PLC input can directly read the 4-20mA signal which is used as a value in the circuit setting …thankyou

[@realpars]

Hi there, Thank you for your question! Like the rest of the PLC, the input analog boards are made with various electronic components like transistors, MOSFET, OPS, A/D converters, resistors …etc. The input analog board’s first measurement stage is mainly the A/D converters’ IC chips that take the 4-20mA analog current signal and convert it to digital. It’s a little more complicated than the way it sounds here. Here is a link to help you understand more about the process and electronics. Happy learning!
