I got contacted in Linkedin by recruiters. I had meeting with 3 managers at the same time, basic sharing informatikn and basic IT security questions. after that, silence, never got any feedback, even didn't get a mail with "thanks for your interest", ghosting by recriters.

1st phone round was scheduled after initial phone call with recruiter. Interviewer covered high level application security standards. It went well and 2nd phone round was scheduled. This round was the Worst phone interview I ever had. Interviewer just asked 1 question and expected a particular answer for it which was followed in DELL. I didn't know the expected answer. That's it, interview was over in 10 mins. How would an outsider would know what's followed in dell? Though there are multiple solutions for it, interviewer is just looping around to get the expected answer.
