I applied through a recruiter. The process took 4 weeks. I interviewed at NTT DATA (Atenas, , Ática)
Interview
Lots of technical questions by an expert engineer, difficulty ranging from trivial all the way to hard niche questions expecting detailed responses. Hardly any behavioral questions. A manager oversaw the technical interview and intervened towards the end. They were both respectful and friendly, it was a good experience overall.

I applied online. The process took 5 days. I interviewed at NTT DATA (Bengaluru) in Oct 2023
Interview
It was good but second round was not good as interviewer was not in process of listening. He was in hurry.
First round was very nice question on java8, spring, microservices tested .
Second round was very bad as interviewer was not in position to wait he wanted to finish early interview.

I applied through a recruiter. The process took 2 weeks. I interviewed at NTT DATA (Orlando, FL) in Nov 2023
Interview
I was approached by a recruiter that I thought was from NTT Data but turns out it was actually Nexient (Launch) which is a smaller company within NTT Data. I would confirm which company you are actually interviewing with and look at the interview reviews for that company. My recruiter was not very knowledgeable and didn't give much insight into the process. She didn't respond to questions and didn't follow up to tell me the result. I had to contact her to get a response. She sent me the wrong job description and didn't seem to understand what I was actually interviewing for.
Two Interviews:
1. Technical Interview - 1.5 hours of conversational skill review. It was VERY technical and extremely difficult but the interviewer was very nice and he seemed like a great mentor. The company has very high expectations of its developers and I got the impression it was extremely competitive internally. It wasn't a good fit for me but a good experience overall.
2. Behavioral Interview - 1 hour. Conversational about common questions.

Recommend reading "Clean Code" and "Clean Coder" as prep.
The interview flows with your skillset so it can vary.
