Software Engineer

Candidates typically face a 60‑minute online aptitude test followed by two technical rounds focusing on C/C++ fundamentals, real‑time operating systems, and embedded communication protocols. The final HR round assesses cultural fit and communication skills. Interviewers value clear problem‑solving approach, hands‑on project experience, and a solid understanding of OS concepts.

DEIC-L&T promotes a collaborative and innovation‑driven work culture where engineers are encouraged to experiment and take ownership of projects. The company offers structured mentorship, regular technical workshops, and a balanced work‑life environment, allowing employees to grow both professionally and personally.

B.Tech/B.E in Computer Science, Electronics & Communication, Electrical, or related engineering streams. Minimum aggregate 60% (or CGPA 6.0/10). Must belong to the 2025 or 2026 graduating batch. No active backlogs at the time of joining. Candidates with up to 2 years of relevant internship or project experience are welcome.

Round 1: Online aptitude test (logical reasoning, quantitative, English) → Round 2: Technical interview (core C/C++ concepts, OS fundamentals, embedded systems, problem‑solving) → Round 3: HR interview (fitment, communication, salary discussion)
