I applied through a staffing agency. The process took 2 weeks. I interviewed at Palantir Economic Solutions (Singapore) in Dec 2017
Interview
First Round - The HR would do an assessment over the phone - . The second round would be face to face - 45 mins aptitude test + 120 minutes - Technical interview (whiteboard discussion, Q&A, Code Analysis) Generally they will ask like 4 hours to be blocked for interview which is time consuming. It is draining and time consuming for sure. Half day will be gone.
Interview questions [1]
Question 1
Agile / Scrum, Web APIs, Design Patterns, Task Parallel Library
