Matic Machine Learning Engineer interview questions

Recruiter reached out on LinkedIn. Had a quick call with the recruiter and then a coding challenge. After that, I had an interview with an engineer on the team. The recruiter call consisted of the usual (experience - background - interest ...etc). The coding challenge was relatively easy. It was a take-home. The interview with the engineer was a little challenging. It was a few brain teaser problems. Review probability (Bayes and general probability rules) and algebra rules (how to solve for equations where the variable is the power of a value). I did not do well in this interview but the engineer and the recruiter were super nice. The recruiter even took the time to give me feedback which I really appreciated.
