Technical
Applied on their website and had a chat with the recruiter, then a virtual meeting with the team manager/engineer. The job posting mentioned a lot of skills, but they actually only needed deep knowledge in one specific area. They mentioned the job wouldn't involve any design, which felt like a bad sign for it being interesting. I asked about how the business was doing financially, given they lost money 4 out of the last 5 years, but the interviewer didn't seem to care much, saying the benefits were good enough. This also felt like a red flag for company stability. After the interview, they ghosted me and kept my application status as 'in progress' for over a month. It felt disrespectful and showed a lot of bad signs, so I'd avoid this place if you want a stable career with growth opportunities.

Behavioral Technical
I went in for a senior role interview. The first person I talked to didn't even have my resume, but it didn't matter to her. She didn't know my background anyway, so she asked me questions more suited for someone just starting out, and she didn't like how I answered. Then, I spoke with the manager. He asked me about something from my past work. When he didn't like my response, he implied I hadn't actually done it, as listed on my resume. I decided that wasn't a place I wanted to work and ended the interview right there.

Technical Coding
I got contacted by HR at Silicon Labs about some openings they had. They were looking at my past experience to see if I was a good fit. Then, the hiring manager set up a phone chat with someone on his team. After that, they flew me to Austin for a full day of interviews. It was a packed schedule with 7 interviews in a row, ending around 4 pm. All of them were pretty technical, covering my design skills, programming and scripting abilities, and how well I knew CAD tools. My main tip for anyone else is that this company is super technical with really smart people, so be ready for some in-depth technical questions. The office vibe is hardworking and not really political.
