Changing domain a good idea?
I've got 5+ yrs of presales experience in Financial Services domain. Building more domain experience thru courses too. Working in latest tech - Cloud, GenAI etc.
Got an offer in telecom, manufacturing - same presales role though with a decent hike. Also would be working in these techs only because this is the market now.
Would changing the domain be a good idea now?

Interview Preparation Tips
Interview preparation tips for other job seekers - I was pretty much sure that I would pass L1 round and hoping for L2 round. I was interviewing for Generative AI Engineer. It was full 1 hr. The interviewer was less experienced than me. He asked me about my current work and focused more on previous work. I gave 80% correct answers and still did not make it. Don't know what they were expecting from me. Then I thought, maybe they are just taking the interview for the name sake. Sometimes, rejections are baseless.
