ZEISS Group interview questions

I applied for 2 similar positions of which I was rejected initially. To my surprise I was invited for an interview after a couple of weeks. Consists of 2 stages: 1st with the team lead, then 2nd with HR and hiring manager. The HR was unfriendly and cold. It was very intimidating. I was promised a response on a specified date but I did not get it on time. I had to follow up and overall left me an impression that HR services are a bit weak.

The Team Lead was the interviewer but seemed like he had already made up his mind regarding choosing a particular candidate previously. The interview was scheduled on a Friday afternoon and sadly, the interviewer was Yawning while I was trying to answer his questions
