The overall interview was 3 rounds: 1 hr call going over fundamental information, 1 technical rounds involving with an engineer on the team based and 1 hiring manager panel rounds

I applied for a role with Altera (which was acquired by Intel). Formal interview with three 30 minute segments, each with a different interviewer. All questions were technical. Was confusing since I received a second interview a day after the first, but I'm pretty sure it was unrelated. They asked mostly Leetcode Hards.
