Goldman Sachs Interview Experience | Set 6

Hi, I recently interviewed with Goldman Sachs, and had 4 rounds of interview with them at their campus in Bangalore.

• Round 1 : Technical – F2F
  1. Check if a linked list with 2n+1 elements is a palindrome without using any extra space.
  2. Given an excel sheet with column names mapped to column numbers as follows :

     A-1 , B-2…..Z-26,AA-27…….AZ-52 and so on.

     
     
     

     Now write a function to return the column name for a given column number.

  3. Find if a given binary tree is a sum tree.

  Then a lot of questions around different technologies and languages.

  
  
  
• Round 2: technical + manager

  This round did not have any DS and algorithm questions. I was asked in detail about my project. Then had a lot of questions around java script and java. About different design patterns and web services.

• Round 3: Technical F2F
  1. Given a stack of unsorted characters, and an empty stack, without using any extra space sort the stack elements and place them into the empty stack.
  2. Print all nodes at a distance k from a given node.
  3. A lot of questions around java, collections frameworks, multithreading and so on. (This took a good 25-30 minutes)
• Round 4 : Senior manager cum HR- F2F
  1. Why do you want to join Goldman Sachs?
  2. Career goals.
  3. Compensation discussions.

Thank you GeeksforGeeks for making it so simple and easy.
