So is listening to the websites that is known to be biased towards disgruntled employees and those that fail the interviews.

I would say statistically biased instead of insignificant. Presumably OP associates with very driven people who happen to do well in competitive environments. Glassdoor suffers from the opposite where 100% of people with a grudge go to complain while a smaller percentage of happy people go to write a review.

Opinions of people I know and consider to be friends are of far more importance to me than that of anonymous randos on the internet.

I recently turned down a job offer at a company based upon friend's feedback and went to a lower paying job that had a lot of negative reviews on glass door. So far, at a month in, I havent seen anything backing the negative reviews. I'm happy at this point, and my commute is the best I've ever had. 15-20 minutes door to door.
