Typical interview loop

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

1. 1

   Recruiter call

   Focus: Background, logistics

   A short call covering your role, background and notice period; campus candidates instead start with an online HackerEarth test.

2. 2

   Machine coding

   Focus: Object modelling, extensible code

   You build a small working program in about 90 minutes, any language and internet allowed, then spend about 30 minutes walking the reviewer through it.

3. 3

   Technical and design interview

   Focus: System design, OOP

   An engineer goes through your resume and the coding submission, then asks you to design the system behind it and probes core concepts.

4. 4

   Past-work deep dive

   Focus: Ownership, technical depth

   A focused discussion of one project from your resume and the decisions you personally made on it.

5. 5

   Hiring manager round

   Focus: Judgment, motivation, fit

   A senior engineering leader talks through your achievements, how you approach problems, and why you want to join.
