declined job application

Good day, my concern is with applying for a job or learnership With absa, I have tried applying for almost 3 years now. When I do apply I get an email saying my application is successful for the first step which I need to write my assessment then I will shortly after that I get an email saying unfortunately they won't be taking me at this stage. I have app**** more than 15 times in one year and the worse thing that I have noticed is I'll apply for being a teller or customer care consultant cause that's what I have been doing with another bank, before even tempting to write the assessment already I will get an email saying Thank you for taking time in completing the assessment while I haven't even started at the same day, I know I'm given only 7 days to complete but I get disappointed before even starting to write. I believe my application are more that 50 with absa and what's hurting is when I visited my local branch to apply I was told to do it online and when I looked around the tellers are new from high school so as consultants. If there is another way of applying for vacancies with absa please let me know cause all of this at the end of the day it looks like fly by night.
