First day / First week etiquette

Hi All,

Hope you're doing great! I started my Associate Sales (fixed income) position in S&T today. I wanted to find out from you guys what you think are proper first day / first-week etiquettes. For example, today I tried to go around to introduce myself to the Sales (of course since I work in this team) and trading side on the institutional desks. I didn't go to the corp desk but feel I should since they did interview me too (but eventually the institutional desk was best fit for me). Any feedback would be GREATLY appreciated!

Also, I brought back some sweets from my vacation to share with the team. Thoughts on this? Don't want to seem like I'm kissing ass. I just think ppl will truly enjoy them because they did at my last job.

I know its a stupid question but any responses would be appreciated by industry folks.

Thanks so much all!
