Candidates describe NCR software engineer interviews as fundamentals-first. Reported coding questions sit in the easy-to-medium range: sorting a string without a built-in sort, reversing a linked list, a binary search tree problem, and FizzBuzz-level string and data structure tasks. One senior candidate faced a more practical, design-flavored round with an architect. It started with implementing a method that returns the second-to-last index of a character in a string. It then moved to designing APIs to add ATMs, increment visitor counts, and find the busiest ATM in a given hour. That candidate later wished they had planned the time-window query before coding, so sketch your data structures first.
OOP and database basics come up repeatedly. Candidates mention polymorphism, abstraction, ACID properties, DDL versus DML, and writing SQL queries. One candidate was asked to write programs demonstrating OOP concepts. Be ready to explain each concept with a concrete example.
Resume and project depth matters too. Candidates report walking through past projects, school work, and architecture choices, and one offer-holder was asked how to structure Terraform modules. Formats vary: reported totals range from three rounds to five. These combine phone or HR screens, technical rounds, an on-site or managerial conversation, and HR. One candidate finished in a single day, and another heard back within about a month.
Most accounts describe supportive interviewers and a fair process, though one senior candidate did not receive an offer after a single round. Practice explaining your reasoning aloud, keep your resume claims defensible, and ask your recruiter about next steps.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an early conversation focused on your resume, favorite projects, and challenges you handled. In one case this was a roughly 30-minute phone screen. One candidate described it as conversational rather than high-pressure. Prepare a concise project story and a clear reason for wanting the role.
Candidates report one to three technical rounds. These cover easy-to-medium DSA problems, OOP concepts, SQL and DBMS basics, and detailed project questions. Some mention linked lists, binary search trees, Terraform, or ATM-related API design. Expect to explain your thought process while coding.
One candidate describes a final managerial conversation. An intern candidate had an on-site round about background, university projects, and career goals, which included a facilities tour. Prepare examples of tradeoffs, ownership, and how you handled technical challenges.
One candidate reports a final HR round covering work topics and culture fit. Another described a final panel with medium-difficulty questions and no tricks. Ask the recruiter about next steps and timing before you leave.
