Hi Kritikakapoor,
Tell me about yourself is one of the most common questions you will face in any interview. You can structure it depending on how your interview started. Mostly, you can start it off formally by saying what you are doing, what you have studied, what your skillset/interests are, your hobbies, and just some fun fact to make the interview easy and fun.
Additionally, sharing a problem similar to what I was asked during my ISB interview.

People with a consulting background or expertise in one industry/startup can expect such questions.
Happy to answer any questions/help with interview prep.
