VMware India-Style Machine Coding Round: Format, Tips & Practice Problems
Written and reviewed by Sahil Srivastav
Resource managers have to allocate scarce capacity, honour priorities, and recover when a worker or host disappears. Rounds in the style of VMware India turn those concerns into a compact scheduler or reservation service.
Gronex originals below provide the practice surface; no company question is represented as factual.
What a VMware India-style machine coding round looks like
Build a reservation, quota, or job scheduler with explicit capacity and release semantics. A deterministic in-memory implementation is normally enough.
Expect a failure or priority follow-up. Make ownership, leases, expiry, and release visible rather than hiding them in a status flag.
Explain complexity and persistence after the core demo.
How you’re evaluated
Capacity invariant
Allocated resources never exceed available capacity.
Lease discipline
Expiry and release are safe to repeat.
Fair scheduling
Priority and tie-breaking are explicit.
Recovery path
A failed worker or host leaves work recoverable.
Common mistakes that fail this round
- Allocating before checking capacity atomically.
- Releasing the same reservation twice.
- Making priority order depend on map iteration.
- Using sleep-based expiry tests.
- Losing ownership when a worker fails.
Quick tips for the room
- Write the capacity equation.
- Give leases an owner.
- Inject time.
- Define the retry destination.
How to prepare
Implement a capacity reservation with leases and one worker-recovery path under a timer.

Were these VMware India questions?
No. They are Gronex originals in the style of resource-management rounds. Gronex is not affiliated with VMware.
Do I need real virtual machines?
No. Model resources and worker outcomes as interfaces with fakes.
How do I show recovery?
Make ownership and retry state explicit, then test a worker failure before completion.
What should be deterministic?
Allocation order, tie-breaking, expiry, and release results.
