Yes, I got a data science job advertised as masters only by showing past work and painting a picture of how I could do similar for their industry specific problems. I think credentials are often more a factor in getting the interview which can be hacked through connections and good networking but once you're in the interview, you can often communicate compentency through past work rather than a stamped piece of paper. That said, I've since done a MSc in Statistics and it's definitely easier. Think it helps but not strictly required in all cases (some companies will insist but think especially now with such a shortage of skills, I think you can get away with just a solid portfolio and good networking skills)
