Suggest you to talk with the team members if possible or someone from the company in detail to evaluate the toxicity. Based on the interview,we can't say how toxic company is. Try to get more data/info which will help you to make informed decision. Having said this, if you come to conclusion that the managers or team are toxic, no matter how much they pay, i suggest don't join. After a few months, this toxicity costs your mental wellness, which is more valuable than CTC. When you got multiple offers/switched companies in short term, which I assume you have good skillset which are in demand, so wait for some more time, give more interviews and then shift to good company
