Good luck with your interview!

It's understandable you are feeling for your classmate, but I hope this won't take the edge off your achievements. You have worked hard too. Sometimes an employer has a very specific type of person they have in mind for a job, and it sounds like it may possibly be someone like you.

It sounds like an amazing program and you and your classmate will have gained lots of skills and experience which will hopefully help you in your futures - it might just be that it will take her a little longer, but she still has lots going for her. You have not let her down, if this break is not meant to be for her then keep faith that soon another one will be.

Remember your success does not mean her failure.
