Phone screen with the hiring manager after an internal referral. Quick turnaround; 5 days from submission to interview. I was told by the HR coordinator that this would be a technical phone screen. Interviewer was oddly distant and aloof during the call. Questions were almost entirely generic; I was prepared to go in-depth technically but interviewer didn't seem to want to hear in-depth answers. Gave no follow-up questions either. It was almost like this person was ticking boxes on a clipboard. Very cold and unhelpful about feedback. Seemed rather put off that none of the software I wrote for employers was publicly available on github. Guess what - most employers don't want their proprietary code out in the wild. Call was cut off twice toward the end when it was time for me to ask questions; after the second cut-off they simply didn't call me back. No further contact after that from anyone. Very rude.
