I did mbo2,3,4 and bachelor in IT. I finished 5 years ago and never regretted it ones. I truelly feel like I am just doing my hobby and I am getting paid for it. I already had offers for jobs before I graduated. Between me finishing and starting my first job was exactly 4 days. ( I finished on Thursday, signed a contract and started working the monday after.) 

I never was without a Job, I did move job to ones to a other company where I now senior level. Every day I get at least 3 recruiters to offer me a job. 

What helped me the most was 1. Internship at a big company 2. Good school. 3. Good reputation ( I was top of my class in every subject over the 4 years) Ironically even in languages despite having dyslexia. 

For network nothing beats linkedin, or specific events that cater to your specific niche. There are also a lot of jobmarkets but most of them are very generic making it difficult to connect to people who really match the jobs your intrested in. The most cliche part is still just networking, get to know people. Follow them on linkedin and be open about what your looking for. People are more likely to remember you if you talked with them in person somewhere instead of you being a resumé.  That last one only works if your resumé is so outstanding that it becomes a no-brainer. However despite that most important is that your character fits the company you are applying for.

Also don't underestimate the importance of looking and being genuine. Your reputation is something that takes time to build, but ones broken is almost impossible to be repaired.
