Ever Rejected an offer just for growth in skills

Well, it totally depends on what do you want to prioritise, my friend. I see that you are just 4 years of experience. I am glad that you are staying in your current company to grow your skills. Please stay till you learnt enough and make sure that you get a decent hikes too. At some point of time, you need to prioritise money over skills. Please switch just to fulfill that criteria at that moment. We are all wanted only if we are skilled. Once you reach the higher package, you’d be one of those people standout when company wants to do cost cutting. At that time, make sure they have a strong reason why shouldn’t they fire you.

Switch. Companies et al doesn't matter. You are a wage slave, so you should slave for the highest bidder.

Try to find a remote job, those people generally don't have problems

I have seen both sides of the coin. A friend of mine used to switch companies frequently. He is making way more than his counter parts. Another friend who tried the same had his resume rejected multiple times quoting the he changes companies frequently and but his title remains the same. So he might be doing it for the money. In conclusion it does not matter. There will be companies that will ignore your frequent switching and others that wont. However 3 switches in 4years is a bit much personally. Getting into product gets tougher with experience. Also joining young is a good idea. There are plenty of times that i have had second thoughts after getting a new offer. Excuses like everything is fine here. I am learning. Why should I leave. There are times i have stayed. All the promises of new projects coming and you will get to work on it are never kept. Its just that maybe you dont want to leave your comfort zone. So I would suggest to take the offer.

I would suggest switching. Sometimes we regret not making decisions so it's better to make decisions and go with them. Right now I’m also in somewhat the same boat.
