I think you should quit unless you have a lot of financial commitments. Its great if you have a good runway for 3-6 months, if you dont it’s completely okay live on credit card debt rather than suffering at the wrong place. Do not worry about the 6m tenure, its totally fine leave if you dont like it.
Product Management itself is always kind of stressful by the nature of work itself, and you dont really want additional stress caused by these engineers and managers.
Market is healing slowly and it shouldn’t be a problem finding a new role with 2 months. Go for it, mental peace over anything
