- HackerRank exercise - Phone interview - On-site interview I have been interviewed with many firms in the past few months (accepted an offer from google), this is the worst interview I've ever had. Very small firm that only has a few of programmers, no sales team. The interviewers were very unprofessional. I arrived 10 minutes early and they kept telling me that I arrived 10 minutes early. No hand shake, no introduction. While I was being interviewed, the "CEO" was messaging with his phone (un-silent) all the time, talked while I was talking. Very rude! I was interviewed for an Entry Level position, but I was never asked any algorithm or data structure problems, or any other cs fundamentals (do they even have a cs degree?) .
