Thank you r/Btechtards! + Need advice for my first internship

A big thank you to this subreddit! You guys literally carried me through my Btech years, and now I'm finally moving to the next phase.

I am in my 4th year and just landed my first ever internship! It’s a 12-month role starting next month. But honestly, I am very nervous because I have 0 work ex.

I am a naturally shy person, so I struggle with things like introducing myself, interacting with colleagues, and working in a team. Logon ke saath kaise behave karna hai aur team mein kaise kaam karna hai, mujhe sach mein nahi pata

You guys guided me through college, please guide me through this corporate transition too. Ek nervous fresher ke liye koi tips? How should I approach my first few weeks? Thanks in advance!
