TransPerfect Project Coordinator interview questions

I was apparently overqualified for whatever I applied to before so they recommended I applied as a Project Coordinator. I said sure. They gave me a HW assignment to find the mistakes in the translation. I found the amount they specified (50 in one doc, 25 in the other) then they told me, yeah sucks to suck, we're not hiring you. Pretty sure they're just scamming people into doing their work for them cause they keep listing the same job listing daily on Linkedin. What a waste of my time and effort.

The process began with a phone interview with a recruitment coordinator, which was very pleasant and informative. Following this, I was scheduled for an hour long video interview with a manager. This video interview was scheduled to be with one person, however, when I entered the meeting there were two people awaiting me, already in discussion. I was caught off guard, thinking maybe I had entered a reused link and was interrupting another interview. The two people did not greet me or reassure in any way that I was where I was supposed to be, instead just immediately moving forward, forcing me to ask outright if they were speaking to me. Because of this, I felt embarrassed and had a hard time connecting for the first stretch of the interview. My reaction is on me, I just wish they had let me know that my interviewer/s changed so I wasn't blindsided and confused.
