The recruiters from square contacted me more than 1 time. I reached out when I started looking for jobs. They set up a time to talk to the recruiters and explain the position and then if you are in san francisco you have 1 telephone/coderpad round. If you are out of san fran, you have 2 tele/coderpad round before they fly you in. The recruiter told me that the telephone screen is a pair programming interview, which is complete farce. The guy just copy pasted 100 lines for a question and then kept working on his computer, his computer would beep all the time and he didnt say a word. I was trying to engage him by explaining my thought process but he couldnt care less. He gave me a hard leetcode question and I couldnt solve it in 45 mins. He asked me to do line justify a given paragraph. I dont know how doing a line justify is related to their business model but again, the interviewer couldnt care less. When the recruiter sends you the email, they would ask you to run your code frequently, but every time I did it, my interviewer was judging me hard. I wouldnt advise anyone to spend hours preparing for pair programming or giving rounds after rounds in this company. If you can clear interview here, you will be able to clear at other places and there are much better companies out there.
