Yours is a bad example. I on-boarded at a remote-first company (they were remote pre-COVID) a year ago and my experience was nothing like yours.

I was warmly welcomed and immediately partnered with a senior person. People were extremely helpful and if I needed help, people were always open to hopping on a call to get me unstuck. Most people respond to slack messages quickly.

The only downside is the codebase/tech stack sucks and the technical culture leaves something to be desired. But they have really nailed the remote experience.

I will never willingly go back to the office. My employer definitely gets more productivity out of me than if I were in office. It really is a win-win in my case. [Edit]:removed repetition
