I was contacted out of the blue by a headhunter. I hadn't heard of the company before and I almost declined to pursue the opportunity. The recruiter asked for my desired salary and after I responded, he countered with more which go my attention. Phone interview was first, basic tech questions about SAN infrastructure, and basic RAID differences. The phone interview questions were scripted so all candidates get the same questions and likely the same order. I hung up the phone with a feeling that I nailed it. Face to face interview was with 2 people, 1 manager, and one super tech. More technical questions to feel out my understanding of SAN and tech level came out. More basic networking and SAN troubleshooting scenarios were asked. At one point they gave me a laptop and asked me to determine the cause of a problem on their product. The given info was a performance graph, and a log file accessible via SSH terminal. I'm not terribly fast when typing on a laptop, scanning a log from a system that you are unfamiliar with, and nerves worked against me. I could ask questions about any line item in the log. Overall, I'm surprised I found the answer. Manager asked some questions off and on to feel out my personality. After the 2 person panel, I was supposed to meet with the site manager, but due to scheduling issues, he couldn't talk and settled with a handshake and hello. I left with my head spinning with RAID 4 vs 5 performance and rebuild comparison questions. I hoped they were asking me the questions to determine my thought process vs knowing the absolute right answer. Post hire I asked about this and they were indeed trying to determine my thought process. I'm still not sure about the right answers to the questions.
