Mercor Software Engineer interview: a three-part HackerRank-style OA

After applying online, I received an online assessment on HackerRank-style tests with three sections. It covered data structures and algorithms, data pipelines, and SQL questions.

Not long afterward, I had a 30-minute conversation with the hiring manager. It was mostly behavioral, with a few technical discussions mixed in. It felt like a standard early loop, with the OA setting the tone and the recruiter-style screen focused on how I think and communicate.

Location: Taiwan. Overall feedback: positive. Offer status: no offer.
