Tech Mahindra Senior Software Engineer Java Developer interview questions

got a call from COGBEE to schedule an interview for Tech mahnidra. in First round of interview asked me some basic question of core java, springboot and one coding question. It was a nice interview and I was pretty sure that I am going to select for the next round but when called the HR, he said unfortunatelly you didn't cracked the interview and I was shocked. the process of hiring by COGBEE need to re-check by the tech mahindra team.
