  1. One easy sorting based question
  2. Shortest Path problem(BFS)

Both were doable in the given 90 mins time.

2 rounds of technical interviews were scheduled.

Round 1:

  1. K largest Elements of the given array. (Using Heap). As a follow-up was asked to Implement Heap. I was not able to implement the max heap.
  2. I was able to give the approach but was not able to give the code properly.

Overall the round did not go well. Was my first interview after a very long time, so was kind of nervous. The HR told me the second round had to go really well if I had to move to the next rounds.

Round 2:

  1. Given a file having a timestamp and some log in every line. Retrieve all the logs that depict certain errors. (Basically, the coding style was checked here. if we declared the classes properly, constructers, getter-setter methods and the standard naming conventions, modularity, etc.)
  • I was able to answer both questions with great clarity. There were many follow-up questions for the 2nd one, she dug into corner cases and was satisfied with the way they were handled.
  • I was pretty confident that the round went really well and hoped to the interview to proceed further. And yes, I did. 

The hiring Manager Round and another technical round were scheduled.

Round 3:

  • Hiring Manager Round – All LP questions, reasons for change, expectations, and other common questions.

Round 4 :

  1. Technical Round – 40mins LP questions
  2. Easy and done. Have given the approach and coded in 10mins that were left.

Both rounds went well IMO, but it’s all subjective. So you are never sure. I was hoping that I’d be offered the role, but hard luck, Apparently they had concerns about my coding(the 1st round that didn’t go very well).
