The process took just a week. HR contacted me as she liked my LinkedIn profile.

We scheduled a half-hour interview with a lead title holder, but the interview was postponed twice. During this process, they shared a HackerRank challenge to be solved in three days. So, I had the interview and the challenge on the same day, but the interviewer was a new person.

Interview Experience:

• Asked academic project-related questions.
• Disadvantages of TF-IDF, as the interviewer saw that term on my resume.
• What data structure would you use to find the longest word starting with "CATER" when given a dictionary of words? (The words could be CATERS, CATERERS, CATERING). Output should be Catering.
• How do you access private variables from outside a class without using getter and setter methods?
• Explain about heap and stack memories.
• Is the garbage collector called on the heap or stack?
• Explain about the Decorator design pattern.
• Explain about Comparator and Comparable.
• Difference between HashMap and HashTable.
• What is a Hypervisor?

HackerRank:

A problem on Roy's lucky number and another problem on overloading the methods of Comparator.
