Question Details
ROUND-1 I. Field of interest(I told data structure and problem solving) II. project III. How to find whether a loop in a linked list is present or not & if present then find the point of loop. IV. An array consists of only 0,1 & 2 in an unsorted manner.sort the array. V. 8 queens problem(backtracking) VI. Coins with weight puzzle:100 bags with coins like 1st bag has 1 coin,2nd bag has 2 coins & so on.all the coins weigh 1gm but only one bag has coins with weight of 1.1 gm.identify the bag. VII. Swapping problem using pointer.(he wrote a code where input values for a,b variable has to be swapped.asked me to write the arguments for the function he used using pointers) VIII. Puzzle-4 person & a torch light problem. Round 2 • Given the inorder and preorder traversals, find the binary tree corresponding to them. • Given an array of integers and a value k, find a pair of array entries whose sum is equal to k. Brute force approach will not be considered. • Given a binary tree with parent pointers to every node in addition to the left child and right child pointers and a pointer to the root and a pointer to any node,
return the mirror node. What if the pointer to the root is not given? • What do you know about design patterns in Java? • How does singleton design pattern look like? • How to make the singleton design pattern thread-safe?

Infybeam Interview Process Overview
The Infybeam interview process typically includes a recruiter screen, one to two technical phone screens, and a 4-6 round on-site or virtual on-site loop. Each round serves a distinct calibration purpose: coding rounds measure correctness, code quality, and complexity reasoning; system design rounds measure architectural judgment at the appropriate level; behavioral rounds measure ownership, leadership scope, and collaboration. Reports tagged on LeakCode from 2024-2026 show Infybeam runs a calibrated process consistent with industry norms for companies of its tier.
Difficulty calibration: Infybeam coding rounds typically run medium difficulty with follow-up depth as the senior discriminator. System design rounds expect production-grade trade-off articulation at L4+ levels. Behavioral rounds expect quantified outcomes ("reduced p99 latency from 800ms to 120ms") rather than vague impact claims. The candidates who advance consistently demonstrate clear thinking out loud rather than perfect final answers.
How To Use Infybeam Question Reports
Real candidate-reported interview questions are a calibration tool, not a memorization target. Infybeam updates its question pool every 2-4 months; memorizing exact problems risks misleading you when the interviewer uses a variant. The high-leverage approach: identify the patterns that appear repeatedly in Infybeam reports, practice those patterns on similar (not identical) problems, and use the reports to understand the interviewer's typical follow-up depth.
Filter the questions above by round type, difficulty, and recency. Focus first on reports from the past 6-12 months; older reports may reference questions that have since rotated out of Infybeam's pool. Reports tagged with quantified difficulty and explicit round type are higher-signal than reports without those tags. The metadata filters help you build a focused study plan in 1-2 hours rather than 8-10 hours of unstructured browsing.
Common Infybeam Interview Mistakes
Reports tagged "no hire" at Infybeam consistently surface a few patterns: jumping into code without clarifying requirements, coding silently for extended periods, missing edge cases (empty input, single element, large input, overflow), producing working code the candidate cannot refactor when probed, and behavioral stories that use "we" instead of "I" diluting individual signal. Strong candidates explicitly avoid these patterns by following a consistent round template.
The single most predictive failure mode in recent reports: not asking clarifying questions. Interviewers are explicitly trained to weight this dimension. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into implementation immediately. Strong candidates also verbalize their approach before writing code; weak candidates code in silence and lose the communication dimension of the round's calibration.
