Don't send hundreds if applications. Find jobs you want and positions where you are a good fit (know relevant Lang platform at least from school or hobby project etc). If a position asks for an experienced person - don't bother applying! Send a small number of very good applications.

A junior position at a mobile games place should definitely be a good fit if you can show a portfolio of such personal projects.

Find people to review your resume and letter. Pay for that service if you can't find friends or people e.g here on HN. Make sure to find people in your own job market to do this - so if you are looking for work in Germany then find Germans to ask for help. What's expected in an application is very regional.

Go to meetups and talk to people.

Finally, when you are rejected after an interview, ask someone for feedback on your application and interview. Ask them to be open about what you could improve. It could be something trivial like spelling.

Hi,

I used to send 1~2 application each week between the time when I was still a student and couple weeks after my graduation. But as times goes by, I started to increase the rate.

As others have pointed out, something doesn't seem right.

There is a red flag in your application and you need to find it.

Are you 50+ years old? A non-citizen (visa required etc)? Degree is from a foreign school?

If no to all of the above then you should be fine as soon as you had a few people review your resume.

If you answered yes to any of the above then the situation may be different.

Edit: ok I checked your profile - you are based in Dublin, and you are not 50 years old... Given your Chinese(?) background, do you have any problems working in Dublin (visas etc) that might scare an employer? Are you a citizen so you are free to find work anywhere in the EU? Would you want to move?

I'm not foreign citizen. I just added my citizen status on my resume.
