What Is the Trade Republic Interview Process Like? (Round by Round)

Candidates report four to six stages at Trade Republic, and Glassdoor reports an average of about 23 days to hire across all roles. Engineering reports describe a short intro call first, then a take-home project, then a technical interview about the code you submitted. After that, candidates report a system design interview with two senior engineers, and a final behavioral interview with two engineering managers.

Individual reports describe processes of about three weeks to about two months. Trade Republic is a mobile broker that also holds a full banking license, so the stages differ by role and by level.

Quick Overview

Stage 1: Application and CV Screen

The form asks for your CV, your current employer, your job title, and your LinkedIn profile, while a GitHub profile is optional. Multiple choice questions cover your location, whether you need visa sponsorship for Germany, and your years of backend experience. Two more ask about Java or Kotlin familiarity and cloud experience.

There is also one written answer. Candidates report a CV screen before any call, so write it with care, and read the guidance in how to answer why Trade Republic. The question is: "What excites you about the opportunity to join Trade Republic?"

Stage 2: The Intro Call

One candidate reported a 15 minute call with a staff engineer. Introductions lasted about five minutes, and two questions about past work lasted about eight minutes. One or two minutes were left for the candidate's own questions. Other reports describe a recruiter call instead, and some describe a first call with a director.

Expect the motivation question in this stage, and ask what the remaining stages are, because several candidates report learning about the take-home project late.

Stage 3: The Take-Home Project

Candidates report a take-home project after the first call, with about five days to submit it. One backend report describes implementing a set of API endpoints. Another describes the task as a mix of a data engineering problem and backend work.

A frontend candidate reported building a small app that used websockets. A websocket is a connection that stays open, so a server can send price updates without being asked each time.

Candidates describe the project as comprehensive and slow to finish. Submit code that runs, with tests and a short README that explains your choices, because some candidates report written feedback on the submission.

Stage 4: The Code Review Interview

Two senior engineers discuss the project you submitted. They ask what you wrote, why you chose it, and what you would change with more time. One reported account also includes a live task, such as implementing a class that solves a small real problem. Name your trade-offs before the interviewers ask about them.

Stage 5: The System Design Interview

Two senior engineers run the design round, and the reported questions match the product directly. One candidate reported this question: "Design the infrastructure that regularly executes saving plans". Another reported a question about implementing an automatic investment tool that runs every billing period.

Both are scheduled jobs that move customer money, so correctness matters more than scale. The full topic list is in the Trade Republic system design interview.

Stage 6: The Behavioral Interview

Two engineering managers conduct this round, and both ask about past work in detail. One reported question asks about the most difficult task in a project, and how you communicated with stakeholders.

Trade Republic states its mission as empowering everyone to create wealth with easy, safe and free access to the financial system. Prepare stories about ownership, careful releases, and work with risk or compliance colleagues.

How the Process Varies by Role

Not every reported process matches the backend sequence above. One frontend candidate reported four stages across three weeks, ending with a culture fit round. Data science candidates report three rounds and no online coding test. Ask the recruiter for the exact list before you begin.

Timeline and Decision

Glassdoor reports an average of about 23 days to hire, from a sample of about 81 submitted interviews. Engineering reports describe longer processes than that average. Glassdoor rates the difficulty at about 2.74 out of 5, and about 53 percent of candidates who rated the experience rated it positive. Slow communication is the most frequent complaint, and the reported waits are collected in how long it takes to hear back.

Questions to Ask Them

Every round includes a few minutes for your questions. Ask how savings plan executions are tested before an execution date, and how on-call works during exchange trading hours. Ask what the banking license changes about code review and release approval. A question of that kind also proves you read the product documentation.

How to Prepare

• Drill patterns, not puzzles. Grokking the Coding Interview covers the patterns behind the take-home project and the live task.
• Practice scheduled money systems. Grokking the System Design Interview teaches the queues, jobs, and databases the savings plan question needs.
• Treat the take-home as production code. Tests, a short README, and clear names are graded alongside the result.
• Prepare two ownership stories. The behavioral round asks about difficulty and about stakeholder communication, so bring one for each.
