Recruiter call went very well and I had a nice chat with them but the pair programming interview went poorly and was by far my least favorite interview I've had in recent memory. The question was not very difficult but interviewer seemed combative the entire second half of the interview which I have not experienced before anywhere else. I solved the first question pretty quickly and when presented with the second question (which built off the first) I started a solution before being told the first answer method could not be changed in anyway. The second question necessitated a change from the first part and when i brought this up I was told modifying the first answer method was not allowed. So i started on a solution talking through my solution and the interviewer would not let it go that I tried to update the first answer method to make the second method far more efficient. I came up with a working answer for the second question but was very much done with the interview at this point. 20 minutes of him bringing up how i can't change the first answer method over and over while i worked on an entirely different solution at that point had worn my patience thin. When asked how I would improve my solution I said I would update what is allowed and modify the first answer to improve overall efficiency in combination with the second method. This started another 5 minute back and forth on how thats not allowed and i would state yes but if im trying to improve the solution thats how I would do it. At this point the interviewer asked me if I had any questions for square to which I said no which seemingly surprised him. No idea why after he was so disrespectful the final half of the interview. I had no intention of working for block/square at this point and wanted the interview to end. I sent an email to the recruiter to revoke my candidacy for the position and very shortly after was sent a rejection letter. I've had many interviews before but never had an interviewer be so combative. Really soured my view of the company which is unfortunate as my call with the recruiter was actually very nice.

I had a call with their recruiter first, talked about my past experience and what I'm look in for in my next role. Then had a technical front-end screening with two engineers where I needed to build an application. I thought I did well, I was able to implement a working app, but I did not pass. Not further feedback was given.
