I did a coding challenge and 2 coding interviews. They didn't seem to care too much about thought process. Speed was very important. You have to know your coding language very well and the concurrency primitives well as well.

Interview process was not quite the most optimal or mutually beneficial. All interviews had a "tricky" part to it, whether trying to validate the person or the skills. Few interviewers were quiet young with only a fewer years of experience and I could sense they wanted me to rush and quickly get to the solution. During the coding round the girl interviewing me was getting impatient with me asking questions and even told me to just get to the implementation fast,
