Allegion Firmware Engineer Interview Experiences

1 interview found

I applied via campus placement at NMAM Institute of Technology, Mangalore and was interviewed in Aug 2022. There were 3 interview rounds.

Round 1 - Aptitude Test 

There were few verbal questions, many questions on electronics basics(op amps, network analysis), embedded c, few general aptitudes questions. Overall it was moderately difficult. EEE and ECE had technical questions under two categories i.e. electrical and electronics . Based on each categories students were shortlisted under firmware and hardware.

Round 2 - Group Discussion 

Group discussion was good. The topic our group got was "Is India ready for electrical vehicles". There were about 10 students in one group.

Round 3 - Technical 

(6 Questions)

  • Q1. Tell me about yourself ?
  • Ans. 

    I am a firmware engineer with experience in developing embedded systems and writing low-level code.

    • I have a strong background in C and C++ programming languages.

    • I have worked on various microcontrollers and embedded platforms such as Arduino, Raspberry Pi, and STM32.

  • Q2. Questions on projects
  • Q3. Difference between diode and Zener diode
  • Ans. 

    A diode is a two-terminal electronic component that allows current to flow in one direction, while a Zener diode is a special type of diode that allows current to flow in reverse direction when a certain voltage is reached.

    • Diodes are used for rectification, signal demodulation, and voltage regulation.

    • Zener diodes are used for voltage regulation and protection against voltage spikes.

    • Diodes have a forward voltage drop, w...

  • Q4. Draw bjt and mosfet model
  • Ans. 

    BJT and MOSFET are models used to represent transistors in electronic circuits.

    • BJT stands for Bipolar Junction Transistor and has three regions: emitter, base, and collector.

    • MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor and has three terminals: source, gate, and drain.

    • BJT is a current-controlled device while MOSFET is a voltage-controlled device.

    • BJT has a low input impedance while MOSFET has a hig...

  • Q5. Different communication protocols
  • Ans. 

    Communication protocols are sets of rules that govern the exchange of data between devices.

    • Some common communication protocols include UART, SPI, I2C, CAN, Ethernet, and USB.

    • Each protocol has its own advantages and disadvantages, and is suited for different types of applications.

    • For example, UART is a simple protocol commonly used for serial communication between microcontrollers and sensors, while Ethernet is a more c...
