Two phone screen discussions with the hiring manager, who was woefully inexperienced for his position.

Four rounds at onsite included two behavioral with the EVP and a manager from a different team.

I have a PhD in NLP and a stellar record. I had interned at top teams for AI/ML (think Google Research grade) during my PhD. I interviewed with Course Hero since they worked on edtech and were a profitable startup, unlike most edtech companies.

After the phone screen, I spoke to HR and explicitly stated all my competing offers (including 2 Big 4). They said they could match. So I went onsite.

The hiring manager posed real problems they had posted in the company blog as interview questions.

The article doesn't have anything interesting in terms of a solution. It also shows that nobody at Course Hero has any depth in basic NLP; I didn't meet one at the interview either. None of my interviewees exhibited expertise in NLP or edtech.

But the discussions with him went at length for 3 hours. If you need me to consult as an NLP expert, I am happy to do so.

One of the software engineers on the panel said they don't have any super difficult problems like in research here, which is not true. They haven't realized that they were solving unsolved problems in edtech/NLP.

I will warn experienced folks to stay away from Course Hero. I am accepting a Scientist position with the Big 4.

The hiring manager posed real problems they had, using the article at https://www.coursehero.com/blog/edtech-machine-learning/ as interview questions. I wasn't aware of this article until I saw it later, after the interview.
