Proton, privacy by default Software Engineer interview questions

HR screening followed by Manager interview (yes they start with the Manager round) followed by live coding and then SD. SD interview is very biased I would say, it is not an open problem so you have to think like the interviewer is thinking, it is a very different process from your usual system design where you build an answer from your point of view, it is basically a sequence of questions that you need to present 2 answers and defend one. You sudden realize why most people fail the process, you have to be lucky to be on the page of the interviewer
