I applied through college or university. I interviewed at Xpanxion (New York, NY) in Sep 2019
Interview
I appeared for their exam. They had a coding on there own portal that uses camera and microphone and it really doesn't work. I had to restart my exam three times and the worst part it resets my code every time I refresh and the clock is ticking in the background. So, overall was very very bad. Please, if you don't have the capability to make a platform to.coduct an exam please outsource it to hackerrank or similar website. The coding round was of 35 minutes and they given a dynamic programming code

Xyz has Russian dolls where small size dolls can fit into large size dolls. No, doll of similar sizes can fit into each other for example doll of size 2 and will only fit into doll of size 3 or bigger than. that and if a doll has already doll of smaller size it can't take another doll of same size. for ex - if doll of size has a doll of size 2 in it already it won't take another size two doll.
