And if you join an engineering company where the engineers pride themselves on data and accomplishments rather than speculations, it may be worthwhile to provide evidence to support your theory than just argue with everyone without anything to it up.

And if you join a company and someone more senior than you with ACTUAL accomplishments and that is respected in and outside of the company tries to take you under his wings and guide you through the corporate landscape, don't dismiss their actual accomplishments as "irrelevant" at the same time boasting about your success in a product for a "niche market that doesn't exist"

And if you join a company, you should not claim expertise in something unless you are an ACTUAL expert and have the knowledge, experience, and accomplishments to back that up. Saying that you're a T7-9 visionary doesn't make you a T7-9 visionary!

And if you join a company, don't dismiss your fellow colleagues and make a fool of yourself because even if you don't work with them now at the current company, you may encounter them again in the future.

I'm not speaking to any specific incident. Just general advice that any new junior employee to any company should follow.

For people skeptical of the other replies here, the reputation of OP is pretty well known... it has almost become a shibboleth of the people that were around during his tenure.
