Lenskart interview process and practice questions
Lenskart sells eyeglasses, sunglasses and contact lenses online and through its own stores, and it runs its own lens and frame manufacturing.

Behavioral questions
Tell me about an experiment you ran that failed. What did you learn, and what did you do next?
A good answer covers
- What you tested and what you expected
- How you knew it failed, and how quickly
- What you tried next because of what you learned
Describe a time you moved quickly to ship something. How did you keep the quality acceptable?
A good answer covers
- Why speed mattered
- What you checked and what you consciously left for later
- The result and the follow-up work
Tell me about a time you took ownership of a result that wasn't formally yours.
A good answer covers
- The result at risk and why you stepped in
- What you did and how you worked with the actual owner
- The outcome
Tell me about a time you handled a difficult customer face to face.
A good answer covers
- What the customer was upset about
- How you listened and what you offered
- How it ended, and what you'd do the same next time
Role and technical questions
How would you design a virtual try-on feature that shows frames on a customer's face through the phone camera?
A good answer covers
- Face tracking to place a 3D frame model correctly as the head moves
- Running smoothly on low-cost phones, with a fallback using photos
- Privacy: what's processed on the phone and what's stored
A customer orders glasses online with a prescription. Walk me through the systems needed to make and deliver them.
A good answer covers
- Capturing and checking the prescription and lens choices
- Routing the order to manufacturing, quality checks and packing
- Shipping, tracking and handling a remake if something is wrong
Store sales in one city are flat while online sales there keep growing. How would you investigate?
A good answer covers
- Footfall versus conversion versus order value in stores
- Whether online is taking sales from stores or growing the market
- Store-level differences: staff, stock, location, local competition
How would you decide where to open the next few stores in a city?
A good answer covers
- Demand signals: online orders by area, footfall, income levels
- Rent, visibility and distance from existing stores
- Starting with a few, measuring and adjusting the plan
How would you reduce returns from customers whose glasses don't fit or don't suit them?
A good answer covers
- Finding the main return reasons from data and customer comments
- Fixes before purchase: try-on, size guidance, better photos
- Fixes after: easy adjustments in stores, and tracking the return rate
How would you keep inventory accurate across warehouses, stores and the website?
A good answer covers
- One source of truth updated by every sale, transfer and return
- Regular stock counts and reconciling differences
- Buffers so the website doesn't sell what a store can't supply
A customer in a store is unsure about spending more on lenses. How would you help them choose without pushing?
A good answer covers
- Asking about their prescription, screen time and lifestyle first
- Explaining options and trade-offs in plain words
- Respecting their budget and decision

- What you'd like to contribute
Have you used Lenskart's app or visited a store? What would you improve?
A good answer covers
- A specific moment in the journey

Tips
- Visit a store and browse the app before the interview, and notice how online and offline connect: try-on, eye tests, store pickup.
- For business cases, use retail metrics: footfall, conversion, average order value, repeat purchase and returns.
- Show speed with judgement: what you'd test small first, and how you'd know to scale it.
- For tech roles, think about performance on low-cost phones and patchy networks.
