I got an offer from solenis 22LPA fixed. Am working in KPMG with very less than what offered. So suggest whether to join?

Doest it look good on resume from big 4 to this which is leading water technologies. Here I get to work on ML apart from being data analytics, here in kpmg I had opurtunity to be managed but only drawback is low salary for 7 years exp

Yeah you can join it, if the location is suitable for you, also choosing the higher salary will always help in future you already have kpmg tag in resume so no need as such to maintain it , you can take this opportunity and can switch later on with more higher hike.
