Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

You are the scrum team's point person with product, front end and firmware teams. Tell me about a time those groups disagreed and how you settled it.

What they are checking: Whether they can represent the team across functions and get to a decision instead of passing messages back and forth.

Tell me about a time you verified that what your team built actually matched what the product owner expected.

What they are checking: Whether they check intent early with the product owner, instead of finding a mismatch at the sprint demo.

How do you mentor less experienced engineers on the team while still delivering your own work?

What they are checking: Whether a senior engineer lifts the team's skill level instead of becoming the only person who understands the system.

What would you do

A firmware release changes a message format and your middleware starts failing in production. What do you do?

What they are checking: Whether they can stabilize production fast, then fix the contract between teams so it does not happen again.

How would you find the cause of slow response times that only show up during peak evening hours?

What they are checking: Whether they use metrics, tracing and load patterns to diagnose, not guesses based on the last incident.

About the work

Describe middleware you have built that sat between front end apps and devices or firmware. What did it actually do?

What they are checking: Whether they have real experience with the layer between apps, cloud and devices that the myQ platform depends on.

Millions of people open the myQ app daily. How would you design an API that sends a command to a garage door opener and reports the result back?

What they are checking: Whether they handle async device communication, timeouts, retries and state that may be stale or uncertain.

How do you scope a new business requirement before your team commits to it in a sprint?

What they are checking: Whether they break work down, find hidden dependencies and give honest estimates before the team is locked in.

How do you keep a large, shared middleware code base high quality when many people contribute to it?

What they are checking: Whether they use reviews, tests, standards and refactoring discipline rather than relying on individual heroics.

What is your approach to versioning APIs that both residential and commercial products depend on?

What they are checking: Whether they protect existing clients while still allowing the platform to change and grow over time.
