Graviton SWE Interview Experience: Packet Receiver and Connected Components
Question Details
I recently interviewed with
Graviton Research Capital for the Software Engineer role. The first round consisted of two problem-solving questions focusing on data structures and graph theory. The interview lasted around 60 minutes. ## Question 1 – Packet Receiver / Ordered Commit A sender transmits packets to a receiver. * Each packet has a serial number. * Serial numbers are positive and strictly increasing for consecutive packets. * Packets may arrive out of order. * The receiver must commit packets strictly in order. * The first packet starts from 1001. * Additionally, no more than 10 packets can be missing in a row (i.e., packet P and P + 10 will never be reordered). You need to design a Receiver class with a function: receive(packet_number) that processes arriving packets and commits packets whenever possible.
Approach 1. Track the next expected packet number (next_commit). 2. Maintain a data structure storing received but uncommitted packets (a set or boolean array). 3. When a packet arrives: * Mark it as received. * If its number equals next_commit, we attempt to commit packets sequentially. 4. Continue committing while the next expected packet exists in the received set. Because the problem guarantees at most 10 packets can be missing, the buffer size remains small and operations stay efficient.
Time complexity per packet:
O(1) amortized. --- ## Question 2 – Connected Components with N Nodes and M Edges Given: * N nodes * M undirected edges * No self-loops * No multiple edges Find: *
Maximum possible number of connected components *
Minimum possible number of connected components ### Maximum Connected Components To maximize components, we should concentrate edges within a small subset of nodes while leaving the rest isolated. Let X be the number of nodes used to place the edges. A component of size X can contain at most: X(X-1)/2 edges We find the largest X such that X(X-1)/2 ≤ M Then: * One component uses these X nodes * Remaining nodes remain isolated Maximum components: N - X + 1 --- ### Minimum Connected Components To minimize components, we should use edges to connect as many nodes as possible. Each edge can reduce components by at most 1. Starting with N isolated nodes: Minimum components: max(1, N - M)
Explanation: * If we have enough edges to connect all nodes → one component. * Otherwise each edge merges two components. ---

Graviton Research Capital Interview Process Overview
The Graviton Research Capital 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 Graviton Research Capital runs a calibrated process consistent with industry norms for companies of its tier.
Difficulty calibration: Graviton Research Capital 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 Graviton Research Capital Question Reports
Real candidate-reported interview questions are a calibration tool, not a memorization target. Graviton Research Capital 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 Graviton Research Capital 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 Graviton Research Capital'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 Graviton Research Capital Interview Mistakes
Reports tagged "no hire" at Graviton Research Capital 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.
