Things can change… very fast and you should always keep your options open. I was working at a company I really liked. I had great managers and a supportive team, I enjoyed the work I was doing and felt like I grew so much as an engineer in a short amount of time. I saw myself growing there and staying long term. It was good… until it wasn’t. One thing I look back on now is the fact that even when I was happy where I was, I would always do interviews.
