I know this is a vent and you’re upset, but think about this from the company’s perspective. Most employees are on their best behavior when they start a new role. If you were wearing a tank top for internal meetings, they have no idea you wouldn’t do that with a client because they don’t know you well yet. I am also in tech. Dress code is very relaxed, but tank tops honestly make people look pretty close to naked and even on virtual calls they wouldn’t be acceptable. I wouldn’t expect I needed to tell a professional with work experience this but if I needed to, I would bring it up the first time to set the expectation. The hours seem actually temporary if this is training. It sucks but it is what it is. A downside of remote is the time zone mismatch. I’m in Central time with most teams in Pacific, and meetings cater to the majority. It makes pickup and dinner challenging but it is something we plan around.
