Process Engineer Interview Questions

For both of these questions, I told them if there was a single correct answer, I didn't know it...but I walked them through how I would handle each question.

Why is an Agile Project Manager interview based on the PMBOK? That's a really, really bad sign. :)

For the second question, I'd probably use either a cost/schedule variance chart... since you can't assume the same budget or schedule for any of the projects, variance against plan would likely be the best way to go.

Break up the problem as much as possible to narrow down the solution. If you are on the right track, they will help you with the solution.

My advice to the technician would be to clean the wafers with acetone, ipa and di water after the acid cleaning, as acid cleaning removes the inorganic impurities but not the organic impurities, acetone, ipa and di water will remove the organic impurities and hopefully the defects will be reduced

mostly the mountains

Hydrate formation Slugging and pressure loss

Pressure loss in the piping, the pumps may need a huge head / energy requirement to push the chemicals through. The different altitudes create a change in the chemical composition, increase vapor pressure which need to be compensated for before being pumped or reacted

Si can be used as a substrate in LEDs, but it cannot be used in the p-n junction because the bandgap energy is too small to produce visible light.

Technically: Yes. But it has an indirect bandgap, so you really wouldn't want to.

The energy bandgap of Si at room temperature is 1.12eV. Since the relationship between photon energy and wavelength is E(eV)=1.24/wavelength(micrometers), one can calculate that Si could emit a ligth in infrared optical spectrum: wavelength=1.24/1.12eV=1.11 micrometers. BUT, Si is indirect semiconductor! And therefore does not emit significant amounts of light due to the requirement of momentum conservation in optical transitions.

Isn't that the purpose of an interview? To see how you overcome difficult projects? Water? Breaks? Comfortable room? How long did this interview last? Did they hold it in the janitors closet too?

Your viewpoint sound reasonable at first but that really depends how you look at it. Remember the interview is a TWO-WAY process. If that is how your future employer treats you, would you want to work for them? Your comment is inappropriate / offensive when you said about holding the interview in a janitor closet but I did not flag you. R U the manager working at Applied Medical? With that slanderous comment, you deserve what you got. Not to mention Applied Medical pay dirt cheap, very high turnover rate & you are expected to work remotely (evenings & weekends).

~3000 barbers. Work your way to the answer.

I got the same answer, based on eight hour work days with 2 weeks of vacation each year. Based on the interviews I have read, if CREE hired the barbers, they would only need 1500, since they would be working 80-hour weeks.

What is your background

Within how much time did you get your final offer after the on-site interview? Can u pass me that info @ dxd303@psu.edu
