American Express Software Engineer interview questions

Was told a few days beforehand that I had an interview on a specific day and they would tell me the day before what time the interview was. This was really absurd, so I reached out to the recruiter to see if there was flexibility since I was in the midst of a very busy week, but the recruiter never replied back to me. There were two interview rounds: behavioral and technical. The behavioral went really well; the engineer was kind and personable. The technical one was a disaster; not only did the interviewer send me LC questions over chat, he required me to write a class, method statements, and import statements to get the poorly-built IDE they use to compile, wasting unnecessary time. He wouldn't answer any questions, talked over me when I tried to answer questions, and showed up to the interview with poor WIFI so there was always a lag when he said something. The questions were not particularly hard (LC Medium at most), but his interviewing style wasted the time I needed to solve the problem. Extremely negative experience overall and wasn't surprised when I was rejected.
