Fast (CA) Frontend Software Engineer interview questions

Overall process was alright - had a technical screen with a senior engineer that went well, they were very nice. Moved on to the virtual onsite - had a good talk with everyone except for my last coding interview. The challenge required some HTML/vanilla JS and not much guidance by the interviewer. They didn't seem to be paying attention, and when I tried to ask questions, they responded, "you just need to figure out what is wrong." Not very helpful .. Maybe I had trouble reading the one link they provided for help on what to do, but I figured it was a pairing session, not someone staring at me stumbling through this challenge that I would probably never do in a job setting. Overall everyone else was pretty nice, but ultimately was not offered the job. Have also heard not so great things about the company, so do with that what you will.
