Narmi Software Engineer interview questions & guide 2026

The following questions are representative of the patterns observed in recent Narmi interview cycles. While individual interviewers may vary their approach, these categories reflect the core competencies the engineering team evaluates.

Technical Coding & Data Manipulation

These questions assess your ability to write clean, efficient code and your comfort level with data processing tasks common to conversion engineering.

• How would you structure a script to transform a large CSV or legacy database dump into our platform's required schema?
• Explain how you handle errors when a batch of data fails validation during an import process.

Preparation for Narmi should be structured around demonstrating both your technical depth and your alignment with the company’s mission-driven culture. Focus your efforts on the following evaluation criteria:

• Technical Proficiency – You must demonstrate fluency in scripting and database design. Be ready to discuss how you handle data integrity and concurrency, as these are critical to the conversion process.
• Problem-Solving & Ownership – Narmi values engineers who take accountability for real-world outcomes. You will be evaluated on your ability to troubleshoot issues independently and your persistence in seeing a project through to completion.
• Communication & Collaboration – Because this role involves working with implementation teams and clients, you must show that you can translate technical constraints into business outcomes. Clear, concise, and empathetic communication is a key differentiator.
• Cultural Alignment – Review the "Narmi Standard." Interviewers are looking for candidates who put the mission above themselves, lead with curiosity, and maintain high standards even when under pressure.

The Narmi interview process is designed to be comprehensive yet efficient, focusing on your ability to solve practical problems and your fit within a collaborative, client-facing environment. You should expect a progression that moves from a high-level technical screen to more granular, multi-faceted evaluations. The process typically emphasizes your ability to apply engineering principles to real-world business challenges rather than focusing solely on abstract algorithmic puzzles.

This timeline illustrates the progression from initial screening to panel interviews. Candidates should interpret this as a path that moves from technical validation to cultural and cross-functional fit. Use this structure to pace your preparation, ensuring you are as ready for a conversation with a non-engineering manager as you are for a coding challenge.

Data Transformation & Scripting

This is the core of the role. You will be evaluated on your ability to write robust, maintainable code for data-heavy tasks.

• Be ready to go over:
• Schema Mapping – How you design systems to translate data from legacy formats to modern JSON/Relational structures.
• Validation Logic – Creating automated checks to ensure converted data is accurate before it hits production.
• Performance Optimization – Techniques for processing large datasets efficiently without timing out or crashing services.

Client & Stakeholder Management

Technical solutions at Narmi exist within the context of client implementations. You must demonstrate that you can work in a high-pressure, customer-focused environment.

• Be ready to go over:
• Managing Scope Creep – How you handle requests from clients that fall outside the initial project plan.
• Technical Empathy – Translating technical blockers into language that clients can understand and act upon.
• Project Accountability – How you track progress and communicate delays before they become critical failures.

As a Software Engineer focused on conversions, your day-to-day will involve deep interaction with data and client-specific requirements. You will spend a significant portion of your time designing and maintaining scripts that move banking data into the Narmi ecosystem. This involves not only writing code but also creating developer tooling that makes the conversion process more repeatable and less error-prone.

You will act as a technical partner to the Implementations team. When a new bank or credit union signs on, you are the one ensuring their historical data—accounts, transaction history, and user profiles—is correctly mapped and imported. You will frequently troubleshoot edge cases, such as malformed data from legacy systems, requiring a balance of investigative skill and software craftsmanship.

A successful candidate will possess a strong foundation in backend development and a genuine interest in the financial technology space.

• Must-have skills

• Proficiency in scripting languages, specifically Python.

• Experience with database design and writing complex SQL queries.

• Strong verbal and written communication skills for client-facing scenarios.

• A demonstrated history of taking ownership of projects from start to finish.

• Nice-to-have skills

• Experience with Django or similar web frameworks.

• Familiarity with data processing libraries like Pandas or Polars.

• Cloud infrastructure experience, particularly with AWS.

• Prior experience in a client-facing or operations-heavy engineering role.

Q: How difficult is the technical portion of the interview? The technical interviews are generally considered fair and practical, focusing on data manipulation rather than "whiteboard" algorithm trivia. Expect to show how you would handle data in a real-world scenario.

Q: What is the best way to prepare for the behavioral rounds? Focus on the "Narmi Standard." Prepare stories that highlight your ability to handle ambiguity, work across teams, and prioritize the needs of the customer over personal preference.

Q: How long does the hiring process typically take? While experiences vary, the process generally spans a few weeks. If you do not hear back within a reasonable timeframe, it is appropriate to reach out to your recruiter for an update.

Q: Is this role fully remote? The position is listed as Hybrid. Be prepared to discuss your ability to work within this model, particularly regarding collaboration with the New York, NY team.

• Prioritize Communication: In every interview, err on the side of over-communicating your thought process. Even if your code is perfect, the interviewer wants to see how you arrive at your solution.
• Be Prepared for Feedback: The team values individuals who can take feedback gracefully and iterate on their work. If an interviewer challenges your approach, treat it as a collaborative design session.
• Research the Industry: Understand the unique challenges of "Community Financial Institutions." Knowing why they struggle against Mega Banks will give you a significant edge in demonstrating mission alignment.
• Own Your Experience: If you are asked about a project that failed or had issues, be honest about what happened and, more importantly, what you learned and how you corrected the course.

The Software Engineer role at Narmi is a high-impact position that offers the chance to build critical infrastructure for community financial institutions. By focusing on your ability to handle data-heavy engineering tasks, demonstrating strong client-facing communication, and internalizing the Narmi mission, you can significantly improve your standing.

We encourage you to review your own project history through the lens of ownership and accuracy. You have the potential to contribute meaningfully to the team’s success.
