Der Interviewprozess

1. 1

   Online application (one application only)

   Offiziell

   Apply via HRT's careers site (Greenhouse). HRT asks candidates to apply to only ONE posting and to indicate interest in other offices/roles in the application questions; it then considers you for all open positions. Algorithm Developer candidates choose C++ or Python for interviews. HRT says to allow up to 2 weeks for application review; next steps come by email. Same process across New York, London and Singapore.

2. 2

   Coding test (online assessment)

   Offiziell

   HRT's student FAQ says technical interviews usually start with a coding test. HRT's own interview guide (2021, written for Software and Algo Engineering roles) describes it as a timed take-home test on HackerRank or Codility, with possible language restrictions by role.

3. 3

   Coding test content (reported)

   Berichtet

   eFinancialCareers (June 2023) reported intern coding-test questions such as an array-of-queries problem, a binary-sum problem and a cipher-implementation problem, with strict execution-time limits. Role (SWE vs Algo Dev) not specified.

4. 4

   Technical phone screens

   Offiziell

   1-2 technical phone/video screens. Length and topics vary by role. HRT's engineering interview guide describes rounds of about 45 minutes (problem solving/data structures/systems, plus a programming round in C++ or Python). HRT's student FAQ says Algorithm Developers draw on maths, statistics and data analysis as well as C++/Python, but HRT does not publish the exact topics of Algo Dev screens.

5. 5

   Final onsite (multi-round)

   Offiziell

   A multi-round final interview (student FAQ). HRT's interview guide describes a full day of back-to-back interviews, which can be virtual or onsite. Interviewers also assess collaboration, how you take hints and how you communicate (thinking out loud).

6. 6

   Fit / motivation questions (reported)

   Berichtet

   eFinancialCareers (March 2026) reports that HRT has a highly academic culture, cares about your choice of modules, and has asked 'What is the coolest topic you learned in class?'
