Ashamed of Myself

Long story short I had an interview for TD's summer rotational program back in May,  and didn't make it past the first round. I knew someone there and he told me I got one yes and the other guy said no. I was very discouraged and felt like a failure that I had networked so extensively and feel like I "failed" the person I knew and the people I had gotten to know in the group. I decided to put my energy and efforts into getting a finance internship this summer(as I previously had none) and told myself once I got it I would go back to networking/recruiting at another bank. 

I finally got an offer in June and have been working there for about 3 weeks now. I feel ashamed of myself that I let this one failure stop the motivation I once had for getting this role and I am worried now that it is too late and all the positions for next summer have been given out. I would really appreciate if anyone knows of any banks that are still hiring. Thanks.
