I’m not a swe but I work in technology doing solutions, so semi technical I guess. I recently did 6 rounds with a company with positive feedback after each round. They told me they needed to get through a few more candidates and would have an answer on if an offer was being made the following week.

1 week turned into 2 into 3. At the end of the third week I lied and said I had an offer and told them that I needed an offer from them or to remove me from candidacy. The opted to remove me.

I was working at a job, so I wasn’t stressing it but the process was just gross

You can dm me if you want. I ran an agency that did SEO for a several years before I sold it in 2021. I’m can’t provide you with much in the ways of strategy anymore but I can give you an idea if your current provider is doing reputable work or not
