Engineers interviewed: 196

Step 2 — Study the right topics in order

  1. Data Engineering / Airflow — 1 questions. Start here — highest weight in technical rounds.
  2. System Design / Ride Matching — 1 questions. Second priority after the first topic.
  3. DSA / Arrays — 1 questions. Cover once the first two topics are solid.
  4. Airflow / Scheduling — 1 questions. Cover once the first two topics are solid.
  5. SQL / Analytics — 1 questions. Cover once the first two topics are solid.
  6. Behavioral — 1 questions. Cover once the first two topics are solid.
  7. Microservices / Communication — 1 questions. Cover once the first two topics are solid.
  8. Redis / Geospatial — 1 questions. Cover once the first two topics are solid.
  9. API Testing — 1 questions. Cover once the first two topics are solid.
  10. System Design / Surge Pricing — 1 questions. Cover once the first two topics are solid.

Step 3 — Practice with real questions

These are the most upvoted questions engineers report being asked at Grab:

Grab Hard Scenario round 5–8 YearsPython

You need to run a DAG that processes 10,000 files daily — one task per file. How do you design this in Airflow without creating 10,000 static tasks?

Grab Hard System Design round 4-8 yearsSystem DesignDistributed Systems

Design the driver-passenger matching system for a ride-hailing app operating across Southeast Asia, where network connectivity is inconsistent in parts of the region. How does that constraint change your design versus a similar system in a market with reliable connectivity?

↑ 27 upvotes · 15 engineers asked this · Senior SDE
Grab Medium Technical round 2-5 yearsJavaPython

Given an array of ride fare amounts collected over a day, find the maximum sum of any contiguous subarray of exactly k rides (a sliding window problem). Walk through the O(n) approach.

Grab Medium Technical round 2-5 yearsSQL

Write a query to find, for each city, the percentage of rides that were cancelled within 2 minutes of being booked, given a Rides table with city, booked_at, and cancelled_at.

Grab Hard System Design round 4-8 yearsSystem Design

Design a dynamic (surge) pricing system that adjusts fares in near real-time based on local supply and demand, without causing prices to flicker wildly for a rider mid-booking.
