I finally met with my mentor today after a month of trying to schedule meeting time. It was relieving to talk to her to catch up and listen to her advices.she was very encouraging and told me that it was not me who had any problems but it was the economy and it was a bad timing to look for job now. She told me she knew people who used to be manager and directors are now applying for analyst jobs, which means that economy must be really bad. Even her company might be going to cut jobs and they already outsourced lots of the jobs many employees are doing right now, so internship must be really rare and competitive.
At least it makes me feel much better about being rejected by so many firms already. I know it is not the end of the world to me right now but this is the first time I experienced the tiredness of job application. They say job searching is a marathon, especially when you want to break into exclusive field like in or consulting or banking, and I am just not that kind of a good runner. I feel so demotivated before my talk with my mentor just because all attempts to network have not resulted to anything bright or potential. I think I may set a bit unrealistic goal when aiming for big 4 consulting or big corporations right now, but I don't know anymore. Maybe I should start looking at smaller boutique Firms and see how it turns out.

Just one piece of advice for myself: it is important to have a firm belief in who you are and what you are looking for to not lose sights of your goals when obstacles are in your way
