I had interview with travel triangle for SDE . There was two technical round both guys was cool and interview process was very nice when i got stuck they provide me hint .

Round 1 Q1. You have a infinite stream of repeated number find top K frequent number from this stream and discussion on this question like which data structure will you use and time complexity etc. Q2. https://www.geeksforgeeks.org/ write-a-function-to-get-the- intersection-point-of-two- linked-lists/ Q3. Given a link list consist of data , next pointer and also a random pointer which points to a random node of the list . how will you make clone of this ? Q4 . Discussion on projects , i have done one project related to OS so lot's of discussion regarding OS concepts. like Memory management techniques , how will you calculate CPU usages ,CPU time ,for a process on run time ?

Round 2 Q1. Design Gmail Chat Server ? Q2. Sort a stack using only one another stack ? Q3. How a array (fixed size can) use like for k stack ? and after this how will you make these k stack to memory efficient? Q4. Discussion on my MVC web application projects.

About Travel Triangle Interview Reports

This question was reported by a candidate who interviewed at Travel Triangle. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.

Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Travel Triangle are the higher-signal extractions to take from this report.

For broader preparation context, the Travel Triangle interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.

How To Practice This Type of Question

Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.

Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Travel Triangle reports consistently are the ones worth investing in; one-off niche problems are not.

During Your Travel Triangle Round

Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.

The single most predictive failure mode in Travel Triangle reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
