Ask HN: How to deal with Interviewer/HR trying to extract information?
4 by Trent_11011 | 1 comments on Hacker News.
I applied for a job at our main competitor. I've had two interviews with them so far and I'm really disappointed. It seems that their HR and the hiring manager is more interested what my current company is doing rather than what my expertise is. Question: How do you navigate such questions? I feel like I ethically can't share non-public information with competitors. But their HR was pushing hard for more detailed info that I basically refused to share. In the current market, I don't have a lot of options so I'm between a rock and hard place. What do?
