Absolutely depends on the person and can take a lot of trial and error. I think it was my 7th one that finally helped my depression (pristiq). Unfortunately the test #1 mentioned wasn’t accurate for me. Weirdly, like the 4th one I tried (Zoloft) helped my ocd but not my depression, so I actually take multiple despite the dangers of doing that.
trying different meds to see what works can be difficult, but it totally is worth it. if you have any other conditions (mental or physical) you take medication for, i recommend getting a psychiatrist to help you find an antidepressant that would work in tandem with / wouldn’t conflict with the other meds. it can take a while to get a referral sometimes, but that can really speed up the trial and error part.
