Screening needs to be done only in C.

Once it is complete, they schedule you for a virtual onsite.

They ask you to SSH to a server.

They expect you to complete two coding exercises:

• One in C again.
• The other in a very high-level language of their choice (you cannot choose).

They are looking for coders, not engineers.

They are not interested in you. There is sarcasm, disdain, suspicion, and superiority in the interviewers' tone. I would never work for these guys.

IMO, these guys are just academic achievers and cannot deal with real-world ambiguity.

Easy questions. There is not much complexity in the problem. The solution is trivial.

They seem to be judging your typing speed, the fluency and working memory of programming languages, not your problem-solving ability.
