Experience:

Tekion visited the campus in the last week of July 2021 for SDE roles (Internship + FTE). The interview process comprised four rounds.

Round 1: Online Coding Round (75 Mins)

  • Conducted on HackerEarth.
  • Consisted of 18 MCQs and 2 coding questions of easy/medium difficulty.
  • MCQs were predominantly Java output finding questions, along with DBMS and algorithm analysis.

Round 2: Technical Interview 1 (around 60-70 Mins)

  • Started with a self-introduction.
  • Discussion on projects from the resume.
  • Core CS questions:
    • Difference between Unique key and Primary key.
    • Indexing and its use in DBMS.
    • Difference between Locks and Semaphore.
    • Paging and Segmentation.
    • Deadlock and its conditions.
    • What are TCP and UDP used for?
    • Why do we use Object-Oriented Programming?
  • The round lasted about 70 minutes.

Round 3: Technical Interview 2 (around 70 Mins)

  • The interviewer started with two coding questions:
    • Given a sorted rotated array and a target, find if the target is present in the array in O(logN).
    • Given a BST, convert it into a Sorted Doubly Linked List and return the pointer to the head of the Doubly Linked List.
  • The candidate explained the logic and coded solutions for both problems.

Round 4: HR Interview

  • Started with "Tell me about yourself."
  • Discussion moved to projects done during B.Tech.
  • The candidate briefly explained 2-3 projects.
  • The interviewer asked if the candidate had any questions.
