The process was not straightforward, and the recruiters don't know how candidates will be interviewed. I was told the interview would be based on web development, but the interview was actually two timed coding challenges within a half hour, based on algorithms and not web development. There's a communication issue between the recruiters and the engineers doing the interviews, which can lead to misinformation toward the candidate. I could have done better if I had been given an accurate description of what the interview was going to be like.

Write an algorithm that finds repeating characters in a string.
