Blinkit Supply Chain Analyst Interview: Rounds, Questions and Preparation

What the job involves

A Supply Chain Analyst in e-commerce, retail, and D2C ensures products move efficiently from suppliers to dark stores or warehouses and finally to customers. Day to day, they track inventory levels, analyse demand patterns, optimise delivery routes, and coordinate with operations and category teams to reduce stockouts and excess inventory. At a quick-commerce company like Blinkit, the focus is on speed, accuracy, and real-time problem solving across thousands of SKUs.

Role and technical knowledge

1. 1

   What are the key differences between inventory management in a traditional retail store and a quick-commerce dark store?

   Highlight real-time demand, smaller storage space, higher SKU velocity, and the need for frequent replenishment in dark stores.

2. 2

   How would you calculate and use fill rate and stockout percentage for an e-commerce category?

   Define fill rate as orders fulfilled from available stock and stockout percentage as lost sales due to unavailability. Explain how these metrics guide replenishment decisions.

3. 3

   What is safety stock and how do you decide the right level for a fast-moving SKU like milk or bread?

   Cover demand variability, lead time, service level target, and the trade-off between stockouts and wastage for perishables.

4. 4

   Explain how you would use SQL to find the top 10 products with the highest number of stockout incidents in the last month.

   Describe joining inventory and order tables, filtering by date, grouping by product, counting stockout events, and ordering descending.

Practical scenarios

1. 5

   A dark store in your zone is showing 20 percent stockouts for fresh produce every evening. How would you investigate and fix it?

   Check demand forecast accuracy, replenishment frequency, supplier lead times, and evening peak patterns. Suggest dynamic reorder points or split deliveries.

2. 6

   You notice that delivery time for one pincode has increased from 10 to 18 minutes over a week. What data would you pull and what could be the reasons?

   Pull order timestamps, rider allocation, distance, traffic patterns, and store processing time. Consider rider shortage, route changes, or increased order volume.

3. 7

   During a flash sale, orders spike 5x but your inventory system shows only 2x stock. How do you prioritise allocation across stores?

   Prioritise high-demand, high-margin SKUs to stores with highest order density. Communicate with category team and set order caps to avoid cancellations.

4. 8

   A supplier consistently delivers 2 days late, causing stockouts. What steps would you take as a supply chain analyst?

   Analyse impact, discuss with supplier, explore alternate vendors, adjust safety stock, and set up a vendor scorecard for on-time delivery.

Behavioural and situational

1. 9

   Tell me about a time you had to work with a team to meet a tight deadline. What was your role?

   Use STAR format. Show clear ownership, coordination, and how you handled pressure without blaming others.

2. 10

   Describe a situation where you noticed a mistake in data or a process. What did you do?

   Emphasise attention to detail, proactive communication, and suggesting a fix rather than just pointing out the error.

3. 11

   How would you handle a disagreement with a senior operations manager about inventory priorities?

   Show respect, data-backed reasoning, willingness to listen, and focus on common business goals like customer satisfaction.

4. 12

   Give an example of a time you learned something new quickly to solve a problem.

   Pick a genuine example from college projects or internships. Highlight the learning approach and the positive outcome.

HR and motivation

1. 13

   Why do you want to work in supply chain for a quick-commerce company like Blinkit?

   Connect personal interest in speed, data, and problem solving with the company's promise of 10-minute delivery. Show awareness of the sector.

2. 14

   Where do you see yourself in three years in this role?

   Show ambition to grow into senior analyst or category planning roles, while emphasising learning and contribution to the team.

3. 15

   How do you handle working in a high-pressure, fast-changing environment?

   Give a real example of staying calm, prioritising tasks, and communicating clearly under pressure.

4. 16

   What do you know about our competitors and how does that affect supply chain decisions?

   Mention quick-commerce peers like Zepto or Swiggy Instamart. Focus on how competition drives faster delivery, better inventory turns, and cost efficiency.
