I interviewed in October 2018 at the BlackRock Gurgaon location. There was one telephonic discussion, which covered basic concepts of J2SE and J2EE. After that, I was called for a face-to-face interview, which included two technical panel discussions. The questions were from basic Java, collections, Spring, Hibernate, and SQL queries. There was also one round with the client, which went perfectly. Each round involved a panel and lasted for one hour. However, after that, I received no response. I even dropped an email to HR for a response, but she hasn't replied yet.

After that, I interviewed there again today at the same location. The process was the same as before: one telephonic discussion, then a face-to-face interview.

The person named Rajesh Gupta asked only two questions: to write a program for array implementation of ArrayList functionality and to write your own cache. He wanted the exact code line by line. When I said I hadn't worked in cache and had no idea, and asked if he could ask something else, he stuck to those questions only. After I wrote what I could, he said to leave for the day.

Write your own code to implement your own cache and all its functionality, including how to use it, line by line, with exact code.

Implement array list functionality in an array. Write each method's code.
