I applied through a staffing agency. The process took 2 weeks. I interviewed at BT Group (Bengaluru) in Feb 2016
Interview
Process took 2 weeks almost, simple process, written test, 1 tech round and HR round,
Written test consists of 35 core java questions and 20 analytical questions. It is quite easy as cutoff is usually very low.
technical round with panel: I was asked questions on design. Not even single question on Core Java. I believe my score in written test was 2nd highest so that might be the reason he did not ask questions on core java. So interview started with singleton pattern, and we spent almost 15 minutes on this very question, I wrote various forms of singleton , how it can be broken and how it can be saved from being broken. So in and out of it. Then related questions like cloning and serialization, reflection. Volatile variables. Then other design patterns which I had used and mentioned in CV. Few questions on multi threading. I applied only for Core Java position so I was not asked J2EE.
HR Round: It was the most simple one. Few HR questions and then salary discussion. BT is a good paymaster. So so issues there.
The interview process at BT group was a very bad experience.
I was called of into BT office to give the interview and was told that all rounds of interview will be concluded on the same day. The interview was scheduled at 1:30 as I reached there I was made to sit in a closed room with no clue of any interview till 4:30 and post the interview I was told that one round of interview will be done online on the next day.
The other online round went well and the hr kept me waiting for the feedback for couple of weeks and was not replying to the mails as well and later she called and said that position is already closed.
The interview process was so smooth i have to give an online test first than got 3-4 interview for the position which was all DSA based questions which you can find on leetcode medium to hard medium and some were easy level too
I applied through a recruiter. The process took 1 week. I interviewed at BT Group (Cheltenham, England) in Jan 2024
Interview
I have autism. I was originally told two weeks in advance that my interview would be a conversation, regarding my current role/duties and myself. On the evening before, the BT recruiter informed me there would be a technical portion at the end of the day.
This left me with one hour to "prepare", before needing to sleep and drive 3 hours to the interview.
Unfortunately, due to how autism affects me, I can't just pivot to being verbally technically minded.
Despite attempting to communicate with the BT representative, they did not answer my calls or email. (and still have not weeks later). I was unable to postpone the technical portion of the interview.
Indirect feedback received via my recruiter informed me that the behavioural/role portion went well, but that the technical did not. As expected.
I did attempt to raise the issue at the interview, but staff did not know what to do or how to handle the situation and continued the process.
I will not be interviewing with BT again as I do not believe they take disability hiring seriously.
