I had a pretty bad experience with them when I interviewed about a year and a half ago. I don't remember all the details, but I recall them giving me (a frontend SWE) a phone screen problem that was all about micro-optimization. I think they wanted me to implement a trie within the last five minutes of the interview or something. After the interview, I emailed the recruiter and said I didn't want to go forward with them.

I'm sure some people here will say DS and Algorithm questions like that are perfectly reasonable to show off CS skills, but the question was just so far removed from anything a frontend engineer could expect to do that it showed that they just had no respect for the specialty and were hiring for the wrong thing.
