I passed a couple exams on the terminal here at work and decided to stop because:
a) It’s too easy. For example, a question might be: “What do you enter to find news on a company?”
b) It’s boring. You have to watch like 10 videos of varying length (20 minutes - 40 minutes) to get the certification.
c) No one cares about it. I personally would not give a shit if someone had this on their resume.
d) Passing these tests doesn’t show you know anything about Bloomberg. The questions ask you functions that may not be relevant to your job, and even if you pass an exam, you will forget what you learned within 10 minutes of completion.
