DEVA (Greece) interview questions

They sent me two different links for an interview with Microsoft Teams. I joined both of them but no one joined from the company, I emailed them to let them know that I have joined the interviews, but they never answered, I've waited exactly the time the calls were supposed to lasted, and 5 minutes before the second call ended, the person from the company joined in, asked me quickly about my experience and said that they wanted a more experienced person (FOR AN INTERN!!) the whole thing lasted 3 minutes, and I'm sure he just joined to tell me that I'm not good for their company (what was the whole point then? Why they even bothered to call me for an interview?). Also, I realized that it's the same company as 7indigo. It was the most unprofessional experienced I ever had, I had to leave early from my job for this interview, they've wasted my time, and they didn't even apologize. Worst interview ever!!!
