I've had a decent (not great, not terrible) role here at Q over the last couple years. I find the work engaging, especially lately.
I had a recruiter call a few weeks back, which led to an interview. I got an offer the next day. The pay is 20% better and I'm confident that this job would be at least as good as my role at Q. I put in my two weeks notice and my boss is "going to get back to me."
Would you entertain/have you entertained a counteroffer from Q before? What can I expect, and will accepting a counteroffer reflect badly on me here in the future?
