I was actively looking for a job change and 2 weeks back accepted an offer. I'm satisfied with the offered salary and after a long discussion, the expectations from the position. I'm currently serving my notice period.
However, I'm still receiving calls for interviews but I decline them stating that I've already accepted another offer. For this I've received arguments like "you can use this as a leverage to ask for more", "why are you declining, you should continue. Maybe it's better", etc.
Is it ethical/professional to continue with the interviews?
If it helps, the locality is Bangalore, India.
