HR call was nice, very casual. We discussed my abilities and resume. The role required AWS. I was very upfront that I had AWS experience, but was not adept at the time. I was asked which AWS tools I was familiar with and I stated them. It seemed this wasn't taken into consideration at all by the engineer who ended up interviewing me. It's not that he asked particularly difficult questions, but he would ask me what my experience in such and such service is. I would state that I don't have any experience with that, and he would proceed to shoehorn in the question he was going to ask anyway. So basically the interview was me being tested on things which I clearly had no reason to know. At some point the interviewer became noticeably angry and decided to end the call abruptly far short of the slotted time (thankfully) These are the kinds of interviews that make this already strenuous process that much more devastating to the candidate. You're pinned against a wall with nothing to defend yourself and in the end you're made to feel that you've wasted their time (even though they didn't use the information provided to make a suitable interview)
