Tripadvisor

Typical interview loop

How Tripadvisor usually runs it for applied AI and LLM engineer roles.

1. 1

   Recruiter screen

   Focus: Background, motivation, stack fit

   A 30 to 60 minute call about your background, why Tripadvisor, and which parts of the stack you know.

2. 2

   Technical phone screen

   Focus: Data structures, algorithms

   A live coding session, usually one medium problem, where you talk through your approach and its complexity.

3. 3

   Take-home (some teams)

   Focus: Code quality, design

   Some teams send a take-home project, sometimes in place of the live screen, judged more on design and code quality than raw output.

4. 4

   Virtual onsite panel

   Focus: Coding, system design, behavioral

   A block of back-to-back interviews: coding rounds, a system design round for mid-level and senior candidates, and a behavioral or culture round.
