The first interview with the recruiter was nice. The technical interview was very bad. Two interviewers were present, and one didn't even turn on his camera. They didn't even look at my homework, so I just spent my time doing that. During the whole interview, they seemed to be doing something else in parallel, not really giving me their attention, as they already wanted to eliminate me from the process. One interviewer asked me some nonsense questions and made comments as well; his English was also poor.

If you're interviewing in EMEA, I wish you good luck to not get into the hands of these two Indian guys. Don't waste your time on the homework assignment, as they will not even look at it. Just focus on the concurrency part.

How would you design an API to receive a PDF file and process it? The service to process is a third-party one.
