I applied to Flexport on November 11 without refferal and received an assessment link on November 21. The assessment consisted of four DSA questions, all of LeetCode Medium/Hard difficulty.

Technical Interview Rounds
HR Screening (January 15):
The HR reached out to discuss the role and provide a brief overview of the interview process.

DSA Round:
This round focused on IP address validation:

Problem 1: Validate whether a given string is a valid IPv4 address (composed of four octets ranging from 0-255, separated by dots).

Follow-up: Given a string of digits, determine if it\'s possible to form a valid IPv4 address by keeping the numbers in sequence.

Example: \'127001\' \u2192 True (can be transformed into \'127.0.0.1\', \'12.70.0.1\', etc.).
I received the result the same day and was scheduled for the Machine Coding Round the following week.

Machine Coding Round:
The problem was to design and implement Splitwise. I was able to explain the system design well but couldn\'t fully implement the Low-Level Design (LLD) due to time constraints.

Verdict Cleared for the

next round.

Hiring Manager Round:
This round focused on:

My previous experience
