4 rounds of leetcode easy questions, some VLSI questions, and questions on the Virtuoso platform. Some of the questions were curated by the interviewer (no leetcode could prep you, but if you knew how to code straightforward enough)

Interview
The recruiter contacted me and then I had a meeting with the head of the team. He asked general questions in my field. Next round I had three more technical interviews. They were challenging and the goal was figuring out how deep I know the field.
