I applied through an employee referral. The process took 2 weeks. I interviewed at Rock Nano (Singapore) in Oct 2019
Interview
More of a conversation and review of your current work. Make sure to know about their company's current direction and use that to determine whether you are a good fit. Was able to take a look around the office for a bit, it's pretty small.
Interview questions [1]
Question 1
They will ask you on your work speed. Expect to be compared to their current members and their own speed at working to deliver the end-product.
