Lower sensitive items like Icecream cannot be delivered more than 2 KM. - Find out List of Restaurant Given Customer and Cart is Empty - Find out SLA(Time to deliver) given cart, restaurant and Cutomer - Parameters should be Configurable like Sensitivity, Max prep time etc Second Round : - Given character a-z find out nth permutation. Where all permutation are only ascending. For e.g Given characters a,b,c. valid permutations are : a,b,c,aa,ab,ac,bb,bc,cc,aaa,aab,aac,abb,acc,baa,bab,bac,bbb,bbc,bcc,caa,cab,cac,cbb,cbc,ccc Go 4th permutation is : aa - Questions about project Third Round with CTO: Design Flipkart Flash sale architecture. 2 million hits and 20k orders in 2 sec.
