Experience: First 4 rounds on day 1 and this are just to shortlist for more rounds on some other day.
Tips: They will focus on almost all the concepts of computer science.You need to practice a lot and start it right now. Should be easy if you have prepared well enough. Use your holidays to start preparing for placements.

General Tips: Sooner you start, better your placement will be as lack of practice & last day study works only for exams but never for interviews. You'll get enough time to prepare for interviews once you get shortlisted. Focus on it even if you are placed already.

College Name: NIT SURATHKAL

I was interviewed in Dec 2016.

Interview Preparation Tips

Round: Technical Interview
Experience: On-site interview (5 hours).

4 back-to-back 45-minute coding interviews, followed by a design interview, with a lunch break with a Googler in the middle.

The first coding interview was a set of (surprisingly) trivial (no algorithms needed) incremental coding questions.

The two next coding interviews were problems straight from the "Cracking the coding interview" book. Even though I divulged that I'd solved pretty much exactly the same problem before, they didn't give me an alternative problem and I quickly coded up a general and optimal solution for the problems. Follow-up in-depth questions were minimal and not hard.

The last coding question was a pure algorithm question related to search trees/tries. No coding required, spent the whole time reasoning about the most effective algorithm. This was a bit of a brain twister.

The design question was related to high-level system design (not OO design) for storage and search in geographic data. Focus was effective search as well as scalability both in traffic and data volumes.

Tips: Read "Cracking the coding interview" or other similar literature. Solve all the problems and you should be good to go. If you solve a bunch of problems at HackerRank (or similar) as well, you'll have the added bonus of training on how to generalize the algorithms.

Interview Questionnaire 

6 Questions

  • Q1. Testing whether every left child's value is less than the right child's value in a binary tree
  • Ans. 

    To test if every left child's value is less than the right child's value in a binary tree.

    • Traverse the binary tree using any traversal algorithm (e.g., in-order, pre-order, post-order)

    • Compare the value of each left child with its right child

    • If any left child's value is greater than or equal to its right child's value, return false

    • If all left child's values are less than their right child's values, return true

  • Answered by AI
  • Q2. Cloning a linked list-like structure
  • Ans. 

    Cloning a linked list-like structure

    • Create a new node for each node in the original linked list

    • Set the value of the new node to the value of the corresponding node in the original linked list

    • Set the next pointer of the new node to the new node corresponding to the next node in the original linked list

    • Repeat the above steps until all nodes in the original linked list are cloned

  • Answered by AI
  • Q3. Finding the nth character in a stream of bytes
  • Ans. 

    To find the nth character in a stream of bytes, we need to read the stream byte by byte until we reach the nth position.

    • Start reading the stream byte by byte until you reach the nth position

    • Return the byte at the nth position

    • If the stream ends before reaching the nth position, return null or throw an exception

  • Answered by AI
  • Q4. Rearranging a string so no consecutive characters are the same
  • Ans. 

    Rearrange a string to avoid consecutive same characters.

    • Iterate through the string and keep track of the previous character.

    • If the current character is the same as the previous, swap it with the next different character.

    • Repeat until no consecutive same characters are left.

  • Answered by AI
  • Q5. Finding the next highest palindrome
  • Ans. 

    The task is to find the next highest palindrome number given a number.

    • Convert the given number to a string

    • Check if the number is already a palindrome

    • If not, increment the number by 1 and check if it is a palindrome

    • Repeat the previous step until a palindrome is found

  • Answered by AI
  • Q6. To canonicalize a directory path
  • Ans. 

    Canonicalizing a directory path involves simplifying and standardizing the path to remove any redundant or unnecessary elements.

    • Remove any consecutive slashes and replace them with a single slash

    • Remove any trailing slashes

    • Resolve any relative paths (e.g., '..' and '.')

    • Handle special cases like the root directory ('/')

    • Normalize the path by removing any unnecessary elements
