Your board powers on but the sensor never responds. What steps would you take to figure out what's wrong?
Tests: Hardware-software debugging
TechnicalMid levelEmbedded Systems Engineer
How do you decide what goes inside an interrupt handler and what gets deferred to a task or the main loop?
Tests: Real-time systems
BehaviouralMid levelEmbedded Systems Engineer
Tell me about a time you ran into a race condition or a priority problem in firmware. How did you find and fix it?
Tests: Real-time systems
TechnicalMid levelEmbedded Systems Engineer
How would you reduce power consumption on a battery-powered device that needs to last a year?
Tests: Power & memory optimisation
TechnicalMid levelEmbedded Systems Engineer
How do you test firmware when the hardware isn't ready yet or is in short supply?
Tests: Firmware testing & reliability
TechnicalMid levelEmbedded Systems Engineer
How do you avoid memory problems in firmware when you have only a few kilobytes of RAM and no dynamic allocation?
Tests: C & C++ for constrained devices
System designSeniorEmbedded Systems Engineer
How would you design a firmware update process for devices in the field so a failed update never bricks them?
Tests: Firmware testing & reliability
TechnicalSeniorEmbedded Systems Engineer
Tell me about the hardest bug you've hit that turned out to be in the hardware rather than the code, or the other way round. How did you prove it?
Tests: Hardware-software debugging
TechnicalSeniorEmbedded Systems Engineer
When would you choose a real-time operating system over a simple bare-metal loop, and what does that choice cost you?
Tests: Real-time systems
BehaviouralAny levelEmbedded Systems Engineer
Tell me about a time you worked with an electrical engineer to solve a problem on a board. How did you split the work?
Tests: Cross-disciplinary collaboration
BehaviouralAny levelEmbedded Systems Engineer
Tell me about a time a small detail, like a datasheet footnote or a timing value, turned out to matter a lot.
Tests: Attention to detail
TechnicalEntry levelGame Developer
Which game engine have you used most, such as Unity or Unreal, and what's something you built in it that you're proud of?
Tests: Game engine proficiency
TechnicalEntry levelGame Developer
How would you make an enemy turn to face the player smoothly instead of snapping around instantly?
Tests: Math for games
TechnicalEntry levelGame Developer
How would you make a character's jump feel responsive and fun rather than floaty? What would you tweak?
Tests: Gameplay programming
TechnicalMid levelGame Developer
Your game drops below its target frame rate in one busy level. How do you find out what's causing it?
Tests: Performance & optimisation
TechnicalMid levelGame Developer
How do you structure gameplay code so designers can tweak values and add new enemy types without asking you every time?
Tests: Gameplay programming
TechnicalMid levelGame Developer
Tell me about a tool or editor extension you built to make your team faster. What problem did it solve?
Tests: Debugging & tools
TechnicalMid levelGame Developer
In a multiplayer game, how do you keep movement feeling responsive for a player with high latency while staying fair?
Tests: Multiplayer & networking
TechnicalMid levelGame Developer
