I asked one of my friends working there for referral and got the interview chance after 2 months. 1st round was solely based on DSA and comprised of 5 questions - top view of binary tree, 3 sum, maximum subarray product in a array, reverse linked list in groups of k, missing and repeating number. 2nd round was a low level design round in which the interview first asked me about the work i have done in my previous company, all the challenges i have faced and some concepts of oops and then he asked me design the news feed of facebook. 3rd round was a hiring manager round in which he deeply dived into my work in my previous company and all the projects i have done so far, challenges i have faced , work culture in my last company, discussion about what can i expect in innovaccer etc. The outcome was positive and i got selected.
