The Karvaan Labs virtual engineering internship is formatted as a remote, production-realistic software development cycle. Interns do not perform mock tutorials; you build and deploy live microservices adhering to strict engineering specifications.
Weeks 1 & 2
Sprint 01: Microservice Engine
Architect resilient token-bucket rate limiters, WebSocket gateways, and cryptographic Merkle leaf generators in strict TypeScript.
Weeks 3 & 4
Sprint 02: High-Concurrency Data
Benchmark and optimize PostgreSQL sharding, Redis caching, and asynchronous task queues under 10,000 sustained req/s zero-drop loads.
Weeks 5 & 6
Sprint 03: Distributed Cloud Deployment
Containerize using Docker & Kubernetes, establish automated CI/CD security scanning, and pass the final 38-point cryptographic audit.
All code submitted during your internship is graded against real-world production engineering rubrics. Submissions must satisfy the following baselines:
- Strict Static Typing: TypeScript projects must compile with zero
any allowances and strict null-checks enabled.
- Git Hygiene: Commits must follow Conventional Commits standard (
feat:, fix:, perf:). PR descriptions must articulate architectural trade-offs.
- Test Coverage: Minimum 85% branch and statement coverage utilizing Vitest/Jest and integration test suites.
- Zero Memory Leaks: Microservices must operate under a strict 4.0 MB heap memory ceiling under heavy concurrent load.
Rather than relying on arbitrary interviewer impressions, evaluations are governed by an open, deterministic grading rubric:
| Evaluation Pillar |
Pass Threshold |
Verification Method |
Status |
| Throughput Concurrency |
10,000 req/s sustained zero-drop |
Automated k6 load injector |
38/38 Mandated |
| P99 Latency Bounds |
< 12ms under peak cluster load |
Prometheus trace analysis |
Required |
| Memory Efficiency |
< 4.0 MB heap allocation ceiling |
V8 Heap Profiler |
Required |
| Cryptographic Audit |
Tamper-proof SHA-256 Merkle leaf |
Digital Signature Verification |
Tamper-Proof |
Every intern who successfully satisfies the sprint milestones receives an authentic, cryptographically signed Certificate of Internship from Karvaan Labs.
Hiring managers and university recruiters can verify your exact evaluated sprint scores, Git PRs, and rubric grade at any time via /verify.html.
Interns who achieve an overall cumulative standing in the Top 10% (Distinction) or Top 3% (Honors) are directly fast-tracked to the final technical round with our hiring partner network, entirely bypassing recruiter screeners and preliminary LeetCode rounds.
Proof of Work requires integrity. All sprint submissions are automatically scanned with AST (Abstract Syntax Tree) semantic fingerprinting and timing heuristics.
Violations Policy: Any candidate submitting unauthored boilerplate, third-party solutions, or unvetted AI generation without comprehension will receive immediate disqualification and permanent revocation of evaluation credentials.
