1. Online Coding Round Platform: Hackerrank / Codility / Company Portal Duration: 60–90 minutes Format: 2–3 coding problems (Data Structures + Logic) Languages allowed: C/C++/Python Topics: Arrays & Strings Bit Manipulation Pointers in C Recursion / Linked List OS-based MCQs (Scheduling, Memory Management) Sample Questions: Reverse a linked list Implement strcpy without using library Count set bits in a number Implement round-robin scheduling logic ✅ 2. Technical Interview – Round 1 Mode: Virtual / Telephonic Focus: Core Programming + OS + Embedded Knowledge Topics Covered: C/C++ concepts (pointers, memory management, arrays) OS concepts (processes, threads, synchronization) DSA: Linked lists, stacks, queues Basics of device drivers or embedded C (if you mentioned projects) Tip: They may ask you to write code or analyze it on a shared screen or in C syntax. ✅ 3. Technical Interview – Round 2 (System Design + Projects) Mode: Virtual / In-person Focus: Project Deep Dive + Real-World Systems Thinking Discuss any projects related to: Embedded Systems / Firmware IoT or Dashboard UIs System-level design (e.g., memory handling, OS internals) May ask you to: Design a simple IoT system Explain how memory is managed in your project Handle inter-process communication ✅ 4. HR / Behavioral Round Mode: Phone/Video Call Questions May Include: Tell me about yourself. Why Semtech? Strengths & weaknesses. Situational questions (working in a team, conflict resolution). ✨ How to Stand Out Mention any work with microcontrollers, sensors, Arduino, or Raspberry Pi. Show hands-on experience with C/C++ and memory-level programming. Projects using React UI for hardware dashboards are a bonus. Emphasize your interest in low-level and systems programming.
