It's all you can do.. and try not to let the disappointment undermine you. When it comes to job searching, sometimes you feel like you're spinning your wheels and not getting any traction and other times it suddenly rains with opportunities. I don't know how the market is there in Germany (though I hear it's getting bad in Europe now), but it's been terrible here in the U.S. so this is an issue many of us have been dealing with. Not fun. But you just have to try your level best and something will happen eventually. Just try not to get burnt out or let it make you feel down.
It's hard to believe sometimes but all I can do is keep trying to move forward. I hope that I hear something soon.
just believe that will be something just right for you.
i too was struggling with my job....i had a really good opportunity last summer but i didn't get the offer and till few months ago i got my current job. allocate about 30 minutes a day into your job searching, sending out your resume and keep doing that until you find something better. i was doing that for almost 2 years....i hope you'll find something soon...
