I have interviewed about a hundred people.
Yes, I'm one of those scoundrels that presents a coding interview.
I look for two things in a coding interview: technical competence, and character assessment.
The number one thing that a candidate can do to immediately ruin their chances: try to lie or attempt to baffle me with bulldoodoo. I've got a very good BS detector.
So if you are interviewing, and you don't know something, say "I don't know." It's hard to do, especially in an interview. But an "I don't know" is not necessarily a strike against you. Whereas BS is a disqualifier.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
