Grab Vietnam Careers Week
Grab announced its first Grab Vietnam Careers Week, held in Ho Chi Minh City from 22 to 26 October 2016, aimed at hiring engineers to improve regional transportation and reduce congestion. At the time, Grab operated on 23 million mobile devices supported by 460,000 drivers across Southeast Asia. The announcement features an interview with Singapore-based iOS engineer Hai Pham and Android engineer Son Nguyen discussing team culture, regular hackathons termed "Grabathons", and relocation to Singapore. Technical candidates undergo a Codility test and are evaluated on clean mobile architecture, testing, and performance maintenance. The engineers also offer advice on apartment hunting through online community forums and adapting to life in Singapore.

Why Test the Design with Only 5 Users
Stakeholders often question whether qualitative testing with only five participants yields reliable design findings. The chosen research problem dictates the methodology, with qualitative usability evaluations requiring smaller cohorts than broad quantitative surveys. Jakob Nielsen's 1993 analysis demonstrated that testing with five participants uncovers 75 to 80 percent of usability issues, after which additional users yield diminishing returns. In agile environments, teams maximize efficiency by iterating designs across successive rounds of five participants rather than testing large cohorts simultaneously. This five-user threshold applies strictly to qualitative usability testing for specific feature flows rather than opinion gathering, A/B testing, or multi-segment user analysis.
