Compass Front End Engineer interview questions

First call was with an internal recruiter, mostly to get an understanding of what Compass does. Second step was a technical phone screen with a Software Engineer there. I am on Pacific Time. Their internal coordinator scheduled an appointment for 11am Eastern, which I was okay with (8am PT). By 8:15am, I heard nothing so I emailed them and they apologized and asked if I could do 11am PT, to which I reply positively. My interviewer calls in 20 minutes late and pastes some code scaffolding into the coderpad and is clearly distracted. It's a spellcheck algorithm. I begin to ask her questions and discuss possible solutions. She admits that she is working on other stuff and tells me to 'just work through the problem' because she doesn't give hints. I start working through the problem with a basic approach and she stops me by saying that although she doesn't give hints, she felt that I was going down the wrong path. I was provided no constraints or really any direction, even when I requested clarification. She left about 3 minutes at the end of the interview for me to ask a few questions, to which she replied with one or two words. Overall, probably the one of the worst technical phone interviews I have ever had.
