I received a call from a recruiter who found me online. This was followed by one phone screen.

I failed the phone screen. The question I was asked related to bit manipulation, something I haven't used since the first year of my bachelor's studies, about 8-9 years ago. I did study for the interview, but I believed the probability of being asked a bit manipulation question was low, given that we are not living in the 1980s.

It was a good challenge, and I updated my interviewing skills. However, it is frustrating to receive questions that are irrelevant to my work. I work on NLP.

By the way, the recruiters were really helpful. My negative point was related to the phone screen. The interviewer was doing his job while interviewing me. I understand this, as I ended up asking my questions several times.

The question was not very hard; if you search with the keywords I indicated below, you can find it. I believe it is not an appropriate interview question. Programming interviews often seem to be about remembering questions you've seen before.

The interviewer asked me to solve a bit manipulation problem related to UTF-8 validation. He also asked about classic questions such as "Why Google?"
