Switching fundas

What are your answers, if you are switching after 2-3 years, just for monetary reasons which is/are acceptable to HRs. Currently working as a Java backend developer with latest tech.

I have joined a company which i don’t like in a month and now i have decided to switch should i inform that to my next employer .

I started at a pre-rev startup for 10K per month internship as an app developer when I was in my 7th semester of engineering. By the 8th semester, i became a full time employee for 6LPA. That was about 12 months ago. I have great rapport with my CTO and CEO. I received an offer for 8LPA from a well known company, my current employer matched it. I received a counter offer for 11 LPA (10+1). Even though I like the people i don't feel overly optimistic about this given the market circumstances. Should I make the switch? Really very confused.

I’ve joined a company recently and I’m planning to switch from here within 6 months . Is it fine ? What should I say when the recruiters asks for reason for change ? Ps : My average switch between companies were around 2.5 yeas.

Just trying to make sure I'm not too childish in taking the decision. Will not quit unless I have another offer though.

Just got a decent offer, considering a switch. Not sure how to approach manager (also co-founder) with this news. Context: 1. Org has no clear set of rules/policies, but I heard notice period is usually 1 month. My joining date is 1.5 months from now. 2. Team is in a chaotic state. 1-2 folks were fired, no replacements have been hired. 1 person is on a sabbatical. Worried manager won't take news positively. 3. Want to leave on good terms, this is my first job, so not really aware of how to have these conversations.

Will that leave a black mark on my profile for the rest of my career and will have to suffer due to that or is it completely fine?

Why switch? Why not switch? What were the motivations that you had when you thought of switching and whether the result was favourable to you or not?
