I get really nervous with timed interviews, ticking clock freezes my mind. Wondering if you have any tips for that. I code in java at my day job but its not really well suited for whiteboard interviews where I have write all this code on the board. Google interviewer was noting down what I was writing on whitboard and said that he will compile the code after the interview. Wondering if you have any thoughts about it, maybe choose something more consise like ruby?
