I applied to UBS via LinkedIn. I got a link in an email to an online test on Java on hacker-rank. I completed the test. One week later, I got a link to another online test but this on Angular 2. That's when I realized that in both the emails, the job code was different from the one one I had applied to. I tried to get in touch with UBS to check on this but was unsuccessful. Don't bother applying to this company.
