MuleSoft Software Engineer interview questions

After a weird phone screen with a third party company that specializes on interviews, they sent me a "noreply" email saying, among other things: "your skillset is not a strong enough match to proceed at this time". What bothers me is that they refer to my skillset, not my performance on this particular interview. I wasn't interviewing for a specific role and the interview was just generic coding problems, so my skillset refers to my skills as a Software Engineer.. Am I not a match for a Software Engineer position? This is just a matter of language but it's important because it changes completely the messageand is very discouraging for people getting started or struggling to get a job!! It's okay to fail, I also failed Expedia and Snowflake at the same time and it's fine. But then I passed the phone/online screens of Zulily, Google, Facebook, Microsoft and Amazon and ended up lading a job with Microsoft. But sure, Mulesoft is the authority to tell me I'm not good enough for a Software Engineer position (at this time, I guess I can't work yet). As a side note, It's interesting how people pass interviews at bigger companies and fail at smaller companies, my friends had the same situation. Btw, the interview was done by a third party, is this people working as a full time interviewers? Can they code or they just go around judging others? Anyways, if you get discouraging feedback, keep preparing and applying to other places, no one has the authority to judge you as an engineer.
