content: Dave -I'm a recent EE grad and have been working professionally as a hardware design engineer for a few months. The company I am working for is growing and I now find myself in the position of interviewing job candidates from time to time. I'm a bit caught off guard with this responsibility; perhaps you could blog to suggest some interview tips directed toward the other side of the desk?When you give someone a technical interview, do you weigh heavily on the analytical/theory related questions or do you prefer more open ended 'design this' or 'how would you solve this' type of questions? Or do you find it better to just ask about their project history and experience? Do you discriminate for particular personality profiles and if so do you have any tips for flushing them out during the course of an interview?I'm a new fan of your blog. Keep up the good work.

content: Not sure if you are already aware of this, but Dave and Chris talked about this in one of the recent Amp Hour episodes (not this week). The job interview tips videos probably also contains some useful tips.

content: That's a hard one, because everyone has different requirements, and different rolls have different requirements too.But in general, as a first pass you want to start by weeding out the people who don't know anything and are generally clueless at the stuff required for the position. That's pretty easy, you simply ask really easy questions and if they pass those without hesitation then they aren't clueless.Like for example a PCB person you might ask them to name some PCB material and common thicknesses or something, or some ways to reduce EMC issues etc.For a micro person you ask about different brands, compilers, problems they have had, do they use forums etc.For an analog circuit designer you might ask some basic opamp stuff.If they can answer the easy "do you know jack" stuff then I've found they inevitably know the more detailed stuff.You might as them details about technical stuff or projects they have worked on in the Resume to see if they are bullshitting.I generally don't like putting people on the spot with actual in-depth design questions or "solve this" puzzles, because I know that good people can get nervous in interviews and get mental blocks. So I try to ask questions that are fairly open ended so I can guide them if needed. My favourite is to give them a PCB and tell me something about it, anything. Prompting with "name some packages", or "do you recognise any devices" if required etc.Actually, the first pass is the Resume, and some are simply immediate bin tossers based on the wording. I've found that in general you ca weed out 80% or so based on working in the resume. Formatting means jack, it's what you say and how you say it. I need to get "the vibe".A big thing is what they have to show off. Someone who doesn't bring anything to the interview (actual hardware, photos, docs etc) generally goes to the bottom of the list, and would have to work a lot harder to impress me.Personally I don't care too much about someones personality, but I prefer people who speak their mind, not the timid "yes sir" type. I like people who aren't afraid to talk back, speak up when they think something is wrong, and have a bit of an attitude.They could be a chain smoking, environment hating, George Bush loving, drug addict, nuclear war mad, fundamentalist christian creationist, cat loving yank with 20 kids for all I care - if they can do the job well then they are in with a shot. I don't necessarily have to like them much as a person, or have much in common with them. I'm not hiring a friend, I'm hiring someone who can get the job done.Passion for electronics and engineering is important. It's obvious if they have it, or if it's just a 9-5 job for them. Not a deal breaker, but it can make a difference if I have to chose between a couple of people. I'll go with the enthusiastic passionate one first.Of course, some of that HR crap comes into it too. Like being able to fit in with the team, company culture etc. I'm very tolerant or personalities, but I know some others in the team or company are not.Dave.

content: This reminds me of a few years back,when I was trying to retire,& by default, ended up with the job of selecting my replacement.We received quite a few applications,but very few people could walk in & perform in this particular messy job.I would get a sinking feeling every time I opened one where the applicant had done all sorts of brilliant things at Uni,obviously intended to do Post Graduate work,but showed no sign of ever having touched any real Electronics.These people made up around 40% of our respondents.--Wonderful people,no doubt,& probably would be a great asset to a large company,but not in a situation where they would be Engineer,Technician,Handyman,all in one.I talked the boss into calling the job a position for a Technician/Technical Officer,not an Engineer,& to add a bit more detail.This cut down the number of over-qualified people,but opened the door for the other end of the scale.Not many got as far as an interview ,but most of these were "all at sea" when faced with RF stuff.We finally found an older bloke who seemed to have what it took,but it was a fairly agonising period.VK6ZGO
