I'm from Aguascalientes, Mexico! now based on New York. Most of my experience is related to code websites and applications, using JavaScript stack-based.
Say YES to everything, sometimes that can lead to work crazy amount of hours.
Work on weekends or after hours, this habit causes a false perception about the productivity of you and your team. So people gradually will keep asking to work like that, specifically, that will end up causing you (and some people too) burnout, frustration and some health issues (the last one happen to some friend already)
Do not refactor on time, sometimes it's better to spend 1 week in something, instead of explaining to your boss something do not have solution anymore and needs to be rewritten
Invest time only in the product, and do not invest time in engineering. People who are not technical will end up saying do A or B is a waste of time, but sometimes, take the time to refactor, simplify, and research how to speed up something will make a huge difference for your team, and the product.
Do no test before push changes
Dismiss other people ideas
Being reactive instead of analytic
Do not communicate things on time
Force people to use your toolset instead of the things they feel comfortable with
Being in a company with no opportunities, this is just a waste of time
Dismiss recommendations without even hear
Force personal opinions instead of facts when making decisions
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
My 2 cents to the list:
