mechanical engineering or computer systems engineering

I’ve recently applied for a transfer to another academic department in my school for computer systems engineering, I’m currently studying mechanical engineering, but i’m not sure anymore if that’s what i want to do, i’m already old now I’m 25 years old and if i they give me the transfer i’ll be starting from first semester, so I’m looking for advice here, should i stay in mechanical engineering i’ve just passed to fourth semester, or should i change my major to computer systems engineering the chance for me getting the transfer is high because of my grades, so it’ll very likely that they give me the pass to computer systems engineering, so what should i do I really like computers (coding especially) since i have memory, but when i enter i was aiming for mechatronics, but they give me my second option (mechanical engineering) since mechatronics it’s very demanded in my school, but now i’m not intereste in mechatronics since i’ve heard that there are not many opportunities for them, mechanical, it’s not really awful i really like the applied physics, mathematics, the design aspect, and statics, so finally my question is should i stay in mechanical and get a masters in computer systems, and maybe from there work in a tech company, or should i change my major to computer systems, I’m really undecided, by the way february 11 they’ll give me the results in case my requests for major change it’s approved, so i hope you can help me guys before that day happens. thank you very much!
