It could be worse, and tech startups like this can have some weird practices. One company I worked at literally burned tech debt. They wrote it down and burned it. (It never really fixed the core problems either. Imagine that.)
Tech startups can be a little cultish at times. I have seen super healthy cult behavior and also super weird cult behavior. Motivating younger engineers can be a challenge, so if it works, whatever. (I never cared about that kind of stuff as long as I got free food.)
As long as nothing turns religious or harmful, I don't care. Good engineers can be some very unique people and most likely have some kind of underlying mental disorder. (I am absolutely not being derogatory! Without a doubt, I am in that category of engineer as well, but I am much older and restrained these days.)
Rock on. Thanks!
