I interviewed for a Senior Frontend Engineer role at Datadog in Paris. The process involved DSA, React UI coding, and behavioral rounds. Despite receiving positive feedback and proceeding to team matching, the offer was rescinded due to internal alignments.

Full Experience

1st Round: DSA
Valid Word Abbreviation - Leetcode problem 408

2nd Round: React UI Coding
Given a JSON data had to build a component to render the data and support follow ups to add Search and Sorting. Nothing complex, but make sure to understand the data shape clearly and ask questions around Search and Sorting edge cases.

3rd Round: Experience Interview
More of past experience discussion and detailed explanation about complex project i have worked.

4th Round: Values Interview
Behavioural questions and some questions about past projects and Tech lead experience.

Feedback:
Got a positive feedback and Team match call was scheduled with two teams for next day. Was also asked to prepare for all the documents related to VISA and Relocation.

***Received a mail few hours before Team match call about internal alignments shift and not proceeding with offer at this time. Was disappointed, but anyways a good interview experience to remember.***
