Initial interview with a manager and an engineer. Mixture of technical and behavioral questions. Was asked to code a couple coding samples on the spot. One of them laughed at me when I was answering one of their questions that felt unprofessional.

Had pretty standard online first round. A mix of technical questions and some behavioral ones, but mostly technical. A few weeks later, they had an in-person interview. This was mostly simple algorithmic computer science questions, such as finding and removing duplicates in a list, and efficiently traversing a tree of numbers. I spoke with three different people, and that whole interview was at least an hour long. I think the interview went well. But then, they never followed up. I sent at least one follow-up email, but they never responded. I get it if I was not a good fit for the role, that's fine. But ghosting me after bringing me in-person interview did not sit right with me.
