Candidate interview experiences
First-hand accounts from people who interviewed at Calix.
System Administrator
The whole thing was done via 30min Zoom calls. It took nearly 3 months from when I applied until my start date, though the holidays definitely slowed things down. My first contact was a 30min Zoom with a technical recruiter. Then I had a call with the hiring manager. After that, I had a few Zooms with people who would be my peers. The final call was with an executive. Everyone I spoke with was really nice and it felt more like a 'get to know you' vibe rather than a super technical interrogation. They seemed to really value finding someone who would be a good fit, which I liked.

Systems Engineer
It was a total of 7 rounds of interviews including one with the hiring manager. The whole process took over 2 months and was pretty straightforward. Each interview was 30 minutes long with a different person, and they were all really nice. After the initial 7 rounds, I had 2 more interviews with VPs. The T&C team was really helpful throughout the entire process.
- Tell me about L2/L3 and what you have done in your company.
- Can you explain what you have been doing in your company and talk about L2/L3?
Systems Engineer
First, there was a phone screen. It was mostly behavioral questions, and it went well, so I got a call for the second round. The second interview was terrible though. The interviewer was rude, spoke slowly, so I couldn't hear him well, and I wasn't sure what he was asking. He had long pauses between questions, and the call even dropped. It was a really bad experience.
- Can you tell me about a technology you're proficient in, including its pros and cons?
