How to land a Grab Software Engineering Interview?

According to an article in February 2021, Grab is on a hiring spree for 350 more employees. These employees will help deliver online financial services in Southeast Asia and support micro-enterprises in their digital transformation. Some departments include artificial intelligence (AI), cyber security, data science, software engineering, and product management and design.

Here are some ways you can score an interview with them!

  • Referral from a friend who’s already working there! Statistically, applicants from referrals have a much higher chance of getting interviewed.
  • A recruiter from Grab reaches out to you on LinkedIn
  • Lastly, you can apply directly - you can find the list of jobs here

Grab Interview Process

Codility Round

From our research, Grab's Codility online assessment contains 3 fairly easy algorithm questions.

As Grab receives thousands of applications at their scale, the main objective of this round is to screen out very weak candidates or candidates who are not motivated enough to prepare and did not put in their best efforts.


HR Round (Introduction + Basic Screening)

The HR round is a casual get-to-know-you chat with the recruiter. You will be asked general screening questions. The questions are straightforward and mainly to screen for obvious red flags, so there’s nothing much you should be worried about.

You can expect some of the following topics.

  • The recruiter will share more about the company and the role you applied for
  • Your motivation and aspirations. This includes why you apply for the role and your motivations for leaving your current position. One piece of advice is to have a strong reason, and not respond with eyes-rolling answers such as “Grab pays well” (even if it’s the truth)
  • Simple behavioural questions (past challenges and how you overcame them)
  • Questions that you might have about Grab.
  • Your availability for the next round of interviews - it would help if you have some visibility on your availability for the upcoming days and weeks

2 Engineering Rounds (Live Coding + Concepts + System Design)

The next stage of the interview process will be 2 back-to-back technical rounds with engineers, which will take approximately 2 hours in total (1 hour each)

Both rounds should contain live coding. 

  • First round will be about Data Structures and Algorithms
  • Second round is around the topics of Architecture and System Design

The difficulties of the questions mainly range between Medium and Hard on Leetcode, with most of the questions being Medium difficulty. Easy questions have been reported too, but they are a much less frequent occurrence. They could be found in the next section of the article.

Tips to ace the technical rounds:

  • Before jumping into answering the questions directly, analyze the problem carefully. 
  • Clarify any questions you have with the interviewers. 
  • Since most questions have more than one solution, state your assumptions and justify your choices.
  • Understand deeply and be prepared for follow up questions on the scalability and trade-offs of your decisions

Hiring Manager (Culture and Past Experiences)

The last round focuses on cultural fit and further assesses your technical skills.

A detailed discussion of your past projects and experiences will take place. This allows your interviewer to better evaluate how you think. As a result, ensure that you have prepared at least one impressive project you know inside and out, including concerns you might have about your system and what you could have done to fix them. 

You might also be asked questions regarding deployment and development best practices.

Grab Online Assessment, Leetcode and Interview Questions 

The questions asked at Grab interviews are always changing. Grab is always trying to stay ahead of the curve. You should therefore study the fundamentals and learn how to approach Leetcode questions instead of grinding and memorizing specific questions. 

These recently asked questions, however, can still provide a good indication of what your interview will be like.

For the following questions, we will indicate their estimated difficulties on Leetcode with the respective emojis
