Experience:

C-DOT visited the campus for a full-time Research Engineer position. Eligibility criteria included a CGPA of 7 CPI or above for the general category and 6 CPI or above for SC/ST/PH/OBC, with age limits also specified.

Round 1: Resume-Based Shortlisting
Candidates were shortlisted based on their resumes. Emphasis was placed on making the resume attractive by including more projects and technical knowledge (subjects + language), and certifications.

Round 2: Technical + HR Interview
This was a single interview conducted by a panel of two people, lasting approximately 25 minutes.

  • "Tell me about yourself."
  • Asked to explain projects and follow-up questions regarding them.
  • "Difference between AI, ML, and DL."
  • "Explain Convolution Network."
  • "Why C-DOT?"
  • "Time Complexity to Find the largest leaf node."
  • "Tell your favorite data structure and its real-world applications."
  • Asked about current Thesis work (as the candidate's specialization was Data Science, most questions were from ML and DL and the ongoing thesis).
  • "Will you be able to relocate to Delhi?"

The results were announced on the same day, and the candidate was selected.

Tips: Be thorough with your projects and thesis (if a Master's student), and the basics of all subjects (mostly Computer Networks, Operating Systems, Design and Analysis of Algorithms, Data Structures, and Database Management Systems). Explore the company's working domain and make the interview interactive.
