How do you get an unspecified number of documents from Boston-California... You have a copier with unlimited paper and ink. You also have one initial phone call to set up protocols. After the initial phone call there is no communication. You have an unlimited amount of envelops with stamps. One page per envelop. How do you get all of the pages to the office in Cali in order.
First round(Technical) : Introduce your self. Tell me about your project. Some questions on our project. Write a code to find index of an element in a left shifted circular array in O(log(N)). Tell me the approach to print elements of a binary search tree in descending order. Some theoretical questions on DBMS and OOPS. Second Round (Technical+Managerial) : Introduce your self. What is the toughest code you have written? Write a code to print mirror image of a tree. Some coding question on DS. What are your future goals? What is your favorite subject in your academics? Write a code to sort an array (any sorting algorithm). What did you learnt from your project? Note: Some people had second round for 20-25 minutes and they were asked some general questions.
Average level Technical Questions
Tell me about a time where you were given a deadline, and how did you ensure you met it?
in tech round they asked me about my projects,that took a significant amount of time.then they gave me a puzzle.u have a x litre and a y litre bucket,how can u extract z litres of water from a tank.(x<z<y). then they asked me about tcp/ip,all the topologies all layers of OSI model(again repeated in next round).then they told me to write a code to create splitted frames using html.then basic stacks ,linked lists and time complexity of sorting algorithms. in next round,he only asked me networks mostly ftp,ssh and manets and again OSI model.he also asked about my family,why i chose computer science,why dell and where do i see myself in next 5-10 years.like that.it was all cool.no deep.just basic overview of tech knowledge was sufficient. in last round,she told me to ask her questions and also asked if i had any doubts about pay and benefits. in each round in the end,they told me to ask them a question. If u r going for interview please ask a question to them.I had asked them whether they can provide me internships or not.they replied affirmatively.
What do you like the most about programming?
Tell me about hash tables
Technical Rounds: First round they asked me puzzles of finding the number of trails needed to find defective piece in given set of balls, if a magical pond with balls in it doubling every day fills pond in 13 days, on which day it will be filled 1/4th, in a horse race of 5 horses at a time, how many trails are needed to get the top 3 horses out of 25 horses and so on of these types. Programming was pgms on liked list like reversing linked list, and some pgms on hashes. He told me to write in java if possible. I used python as it was easier. Second round he asked me to explain difference between switches and routers, explain ARP, write a pgm to find max consecutive one's n zero's equal in number present in the given binary string, some simple puzzles were written on board, he told me to solve them. Managerial round: Third round he asked me to tell any one thing that makes me stand out of crowd in my department (mine was CSE) and explain that thing in detail. Also asked whether i was interested in pursuing higher studies. (Always tell NO for obvious reasons :p ) HR round: This was as usual, family background, strength n weakness about you. He also asked how many times i have been rejected after reaching till HR round and also how many companies i attended before this.
