I remember that my first interview was kind of similar. Though it was a phone interview on Hackerrank Codepair. I was really nervous, and since it was a phone interview, I tried to speak my thought process, which didn't quite work out due to me constantly stammering. So I just took to typing all the time so that my interviewer wouldn't think I was taking too long coming up with a language or copying answers. I started making silly mistakes like using `int sum=0` in python. I took the input as a number, converted it to a string, and then further converted it back to a number, and did mathematical operations on it, trying to solve the problem. Every time I thought I did it, it would get stuck in another case. Ultimately, the interviewer deleted 50 lines out of my 60-line code, and just added a print statement on a variable I was already using for storing things temporarily, which turned out to be the correct answer. Needless to say, I blew the interview. I haven't done an interview since, and I'm gonna be up for it very soon. I'm not sure if I'd do better this time, but I'd be ready with a glass of water, and try to be as relaxed as possible.
