First of all, I wish you the best luck in finding a job.
In second place, I would like to share with you some of what I will think about If I were in your current unfortunate situation:
1. I am currently unemployed. That means I need a job. And I need to find it quickly. You have to be really convinced about that. (and even though you may find it obvious, it will be extremely helpful in your research).
2. I will send my resume to every company I come across. At this stage I am not looking at the quality of the job offers. I am hunting quantity. If I apply for 10 jobs, maybe i two of them will get in contact with me. If I apply for 100 jobs, twenty of them will probably reply (statistically the percentage of reply may even rise a bit): twenty is much better then two.
3. I will apply for a job even when my skills would lead me to think I won’t fit the profile they are looking for. You simply never know. They might not look for you, yet. But when they receive your application they still may consider it for another position, even though that position is not officially open yet.
4. I will use this time as an opportunity. There is plenty of wishes I simply don’t have the time to make them come true. In the mean time I will also study something related to my major, and (as Marina wisely suggested) prepare a fight plan for the next interview I will take part in, considering that the most difficult question to be answered will be:
How long and why are you unemployed? Why should I hire you if your last employer..? Having a fresh and smart answer about that will be extremely handy, and it may require you some days of brainstorming.
5. I won’t make any debt, nor I will swipe my credit card for anything except food/house needs. Another obvious point. But still very significant. I will reduce my personal expenses to my vital needs, waiting for better periods to come.
6. Once offer start to come, even though I will select them carefully, I will go to any interview that is offered to me. I will eventually use the interviews for jobs I am not really interested in as training.
