ashwin12345 I would strongly urge you to go with personal experiences.
The recommendations and the resume... and in part, the interview.... are all professionally focused and so this is your big opportunity to help them get to know you on a different level.
To really create someone who is more three-dimensional than two dimensional.
The way to separate yourself is to help them see you as an individual person and not just another person knocking on their door with a bunch of work accomplishments that they would like to pedal.
Looking for Depth. Poetry. Vulnerability.
So more work stuff would be a missed opportunity here unless it really shaped who you are as a person.
As for your second question, I do not think that it would be wise here to talk about Rotman. It kind of ruins the intentions of the exercise which is to put the focus on you and help them get to know you as a person. The discussion about why Rotman is something you can say for other aspects of the application process.
