It started with a CV screen, then a basic online assessment covering math and verbal reasoning. After that, there was a short phone call interview (around 15 minutes) focused on competency-based questions. This was followed by a Codility test with three questions that took over an hour. The final stage was a 4-hour assessment day. This included a 1-hour-plus one-on-one interview digging deeper into competencies, company fit, and how my skills align with their needs. There was also a group assessment where we tackled a problem, and they observed how well I worked in a team, processed information, and built upon others' ideas.

The interview process at BT group was a really bad experience. I was called into the BT office for the interview, and they told me all rounds would be done that day. The interview was set for 1:30 PM, but when I got there, I was made to sit in a closed room until 4:30 PM with no information about any interviews. After that, they told me one round would be online the next day. The other online round went fine, but then the HR made me wait for weeks for feedback, and they weren't replying to my emails. Finally, they called and said the position was already filled.

Technical Coding Behavioral
So I had an online test first. Then they called me for a face-to-face interview where I cleared one technical round and another round that was technical plus managerial. After that, they told me there was one more round, an HR round. But it turned out to be a scam; a manager took it, and it wasn't HR-related at all. It was fully a technical managerial round again. The interviewer was incredibly rude and arrogant; I don't know how he works there. He was rejecting everyone. For over half an hour, I wasn't even interviewing; it felt like I was arguing my answers. It was a terrible experience. Even though I cleared all the rounds, they rejected me after the last one. I felt it was really unfair.
