I used to have a startup which we had to shutdown 5 months ago. I joined a good company after that as their software lead. Everything related to this job including the work, the team, seniors, the CEO, pay and environment is good.
Now due to my experience in a startup, I am receiving a lot of good job offers ( at least one per week). By offers I mean offer to interview for some pretty good positions.
I am a very ethical person, thus have always said no to them, since I just joined here and I like being here. Yesterday, I told this to one of my friend and showed him the job positions I rejected. He told me that it's a stupid decision to say no. Even if I don't join there I'll get interview experience and will also know my worth.
I don't completely trust this, but I want to know is it a common practice, especially in software industry?
