NTT DATA interview process and practice questions

Behavioral questions

1. Tell me about a time you changed your mind because of someone else's input.

   A good answer covers

   • Your original view and whose input changed it
   • How you made room for their view, especially if they were junior or quiet
   • What the better decision led to

2. Tell me about a time you proposed a bolder solution than the one people expected.

   A good answer covers

   • The expected option and why it wasn't enough
   • Your proposal, and how you handled doubts and risks
   • What happened, including any part that didn't work

3. Tell me about a time you delivered under pressure when the outcome mattered to a client or user.

   A good answer covers

   • What was at stake for them and how tight the time was
   • What you prioritised and what you dropped
   • The outcome, ideally with a number

4. Tell me about a win you shared with a team. What was your part?

   A good answer covers

   • The goal and how the work was split
   • Your own contribution, in the first person
   • How the team celebrated or shared credit

5. Tell me about a time you worked with colleagues in another country or time zone.

   A good answer covers

   • Who they were and what made working together hard
   • The habits you used: written handovers, overlap hours, clear owners
   • What it achieved and what you'd do differently

Role and technical questions

1. Walk me through how you'd plan moving a client's on-premise application to the cloud.

   A good answer covers

   • Assessing the application, its data and its dependencies first
   • Choosing an approach: move as it is, re-platform or rebuild parts
   • Testing, a cut-over plan with rollback, and cost and security checks

2. A client reports that a nightly data load is missing records. What would you check first?

   A good answer covers

   • Which records, since when, and whether the source sent them
   • The job's logs, filters, rejected rows and any schema change
   • Fixing and reloading safely, then telling the client what happened

3. Explain microservices versus a monolith, and when you'd keep the monolith.

   A good answer covers

   • A monolith is one deployable application; microservices split it into small services
   • Microservices help teams scale and release separately but add network and operations complexity
   • Keeping a monolith for a small team or a simple, stable product

4. A client wants to cut support tickets by a third. How would you work out where they come from and what to fix?

   A good answer covers

   • Grouping tickets by type, product, channel and customer
   • Finding the few causes behind most tickets
   • Fixes such as product changes, self-service help or automation, and how you'd track the drop

5. How would you explain a serious technical risk to a client executive in two minutes?

   A good answer covers

   • The risk in business terms: what could happen and how likely
   • The options, with cost and time for each
   • Your recommendation and the decision you need from them

6. For experienced candidates: describe an engagement where the client's priorities changed. How did you adjust the plan?

   A good answer covers

   • What changed and why
   • How you re-planned scope, people and dates with the client
   • The result and the relationship afterwards

Why NTT DATA? Fit and HR questions

1. Tell me about yourself and what brings you to NTT DATA.

   A good answer covers

   • Your background and the skills most relevant to this role
   • One achievement with a result
   • A specific reason for applying, in under two minutes

2. Why NTT DATA, and what do you know about the industries it serves?

   A good answer covers

   • Something specific: a service line, an industry or recent work you read about
   • How your skills fit it
   • What you hope to learn there

3. What would you want to achieve in your first six months here?

   A good answer covers

   • Learning the team, the client and the systems quickly
   • One or two concrete contributions you'd aim for
   • A question back about how success is judged in the role

Tips

• NTT DATA's FAQ says the technical stage can be a live discussion, a case, a problem-solving exercise or an online test; ask your recruiter which to expect.
• Prepare client stories: the hiring manager interview looks at client engagement, communication and adaptability.
• Have a short example ready for each of the four values, especially delivering an outcome and winning as a team.
• Steps vary by business unit, location and role, so read the job post closely and plan for each stage it names.
