I had an interview with the cloud team, backend. I was required to write code in C++/C/Go under Linux environment and had to make sure it complied and pass tests. I chose Go, which is an easy language and also the language they use in their daily work. I wrote code for previous 2 questions very quickly and pass them, then the interviewer took a hard and long question to test me. I explained how I will solve this question but I don't write the code out.
