Company-specific questions

• Tell us how you heard about Zipline and this job!
• Your team is building a robot that is powered with a 35Ah battery. During testing, the robot will run for a maximum of 5 hours before running out of battery, interrupting testing. The team would like to have a better idea of when the robot is going to run out of battery and needs to be recharged. An electrical engineer on your team designs a board to help solve this, with an LTC2944 and a 0.3mohm sense resistor. You are tasked with writing the software to read the accumulated battery discharge, in mAh, at the highest resolution possible. What should register bits B[5:3] be set to, in hexadecimal? (please omit ‘0x’ from your answer) You will need to look up the datasheet to answer this question.essay
• You have two tasks running on a Linux system with SCHED_FIFO scheduler enabled: Task A: SCHED_FIFO, high priority 90 Task B: SCHED_FIFO, lower priority 70 Both tasks share access to a hardware buffer (e.g., a ring buffer for sensor data). Access is protected using a mutex. If Task B locks the mutex first and Task A becomes runnable while Task B is still holding the lock, what happens? (1 sentence max)essay
• List one or two projects you’ve worked on that best demonstrate your experience with embedded systems (3 sentences max).
