Resources/Advice for an Investment Banking Intern

Hi guys, this is my first post here after a long period of being a mere observer. I have managed to land an internship at an international mid-market M&A advisory in Delhi and this is going to be my first stint in IB. I have a background in Equity Research, but have always been passionate about working in IB, and am really excited to finally get an opportunity. I owe a lot of it to this platform and am really thankful. 

To give you a brief description, I completed my Undergraduate from Mumbai University and recently graduated with an MSc in Finance & Investment from a non-target in the UK. My grades were good enough for a target, but I don't have the greatest financial background and decided to not spend an amount that would come up to almost double of what I shelled out. I didn't take out a loan (I don't like being in debt) but instead paid most of it myself, that I saved up by running a company my friends and I had started. The rest was covered by my family and a few close relatives. In hindsight, this proved to be a good choice considering the job market in the UK is quite bad at the moment.

Anyway, not to get off topic, but since this is going to be my first role in IB (a 6 month internship), I would like to go above and beyond what is expected of me and win that full time offer from the firm. As such, I would like to ask you guys if there are any online resources/books that I should take a look at to get myself familiarised with the various functions in IB/M&A/Corporate Finance, and also for getting more proficient in preparing IMs/teasers/pitch decks + financial modelling. Any advice about your experiences starting out, networking and climbing up the ladder would also be appreciated.

Ideally, I would love to hear from people working in IB/PE/VC in India (the latter two because I plan to make a move to the buy side after gaining a decent amount of experience), but would definitely like to hear from others too. If you've made it this far, thank you for reading this and thanks to this community, which has helped me learn and made me laugh each time I came here to forget about a rejection email. 

(P.S. - sorry if this is the wrong forum for this kind of a thing)
