Provide Group interview questions

I was contacted directly by email and had a first interview with the recruiter and a client manager. After that, I had to take a programming test with OO concepts. The 3rd stage was an interview with one of their engineers where I had to answers questions about microservices, software design, and architecture and this should be the last stage. I then got an offer, but suddenly they emailed me telling me that I had to do another technical interview (???). Yesterday, at the end of February, I had this another technical interview that didn't look like a technical interview at all. Then they communicate that they wouldn't proceed anymore without further explanation.

A head hunter contact me with Provide. I did a technical test with Provide and one personal interview. After that I did a personal interview, one technical test and one techinical interview with a Provide's client
