I was reached by a third party recruiter on LinkedIn that connected me to Calix. After 2 calls with this recruiter Calix scheduled the first 45 minutes interview with a Cloud Development Vice President. It was an easy and straight forward conversation with not a single technical question, but questions on past experiences (not too deep in my resume though, just random scenarios). A few days later I was asked to move to the next round for other 5 (five!) 30 minutes interviews. Due to pressure from the original recruiter company I schedule all five in a single afternoon. The interviewers were "Talent & Culture Business Partner", "Senior Manager, Software Engineering", "Principal Software Engineer", "Director, Software Engineering" and "Principal Software Engineer". The director didn't show up and I had to re-scheduled that. Other than the talent & culture one, all were focused in scalability and didn't really focus on how my experience would help the company but on how to solve their issues (it's like asking for a question, but ignoring the answer and keep talking). After completing all these calls I was ghosted by both Calix and the recruiter. When I decided to ask the recruiter about the status of it, it took a few days yet to receive a polite generic negative response stating "It wasn't an easy decision to make after so many discussions, but they are extremely selective in their process and they didn't see this as the right fit for them". Overall, they were all polite and respectful, but I feel I didn't have the chance to even talk about my skill and how I would be able to help the company. Instead I just listened the same talk again and again and at the end they just didn't like me for reasons (?). Long story short: it seems a nice company, with a confuse hiring process and I was not good (lucky) enough.
