Overall, the process was very good. The interviewers were very nice and patient. The technical questions they asked were pretty reasonable as well. However, the last round was a very long and was naturally a bit stressful.

- A basic Verilog coding question, the kind you can find online.

I applied online and heard from the Manager on LinkedIn. The whole thing took about 3 weeks. It was initially for the FPGA Engineer - II role, but they didn't find anyone right, so they downgraded it to FPGA Engineer - I. Then HR got in touch and set up a phone chat with the Hiring Manager and one of his Senior Engineers. The call with the Hiring Manager was mostly about my resume. The Sr Engineer hit me with Verilog questions, which I had to code live on Collabedit. The next day, the Hiring Manager scheduled an on-site interview for the following week. He also gave me a project to work on, which I had to present to a panel. The on-site was roughly 5 hours long and included 7 rounds: 3 technical, 3 managerial, and 1 panel. Everyone was super friendly and made sure I felt comfortable – a good experience overall. The technical rounds started easy and got harder with my answers. They weren't looking for perfect knowledge, just how I tackled problems. Great experience, and I was hoping for a good outcome, but luck wasn't on my side.

So I had a couple of phone interviews, and one of them included a take-home assignment before the in-person interviews. The onsite part had 5 one-on-one interviews with engineers and managers. Lunch was provided, like Chinese takeout.

- How do you handle crossing clock domains?
- What about wire delay?
