Senior Database Engineer (Or Some Such Thing) Interview Experience
Process
I had applied a while back, and after three weeks, a recruiter emailed me saying Groupon was interested.
First, the recruiter I spoke with (different from the one who emailed) conducted an initial call, and the hiring manager spoke with me on a later date. The manager was knowledgeable and pleasant. Initially, he seemed interested, but towards the end, I sensed he had some reservations. Still, a technical phone interview was arranged.
This technical interview was conducted by a person who was not a master of the subject. The questions were bookish and did not measure any problem-solving ability or the range of my experience. My replies were rated based on their match to his answer list.
In the course of one of the answers, I suggested enabling the slow query log. He wanted the exact syntax to do that, which was amusing since the syntax can be Googled in ten seconds.
The interviewer wanted to know what I would do before performing an ALTER TABLE command. I replied, "take a backup." His answer list had "check for space," so my answer was deemed incorrect.
I explained Galera cluster configuration with multiple servers, as used in my current job, which he did not understand.
I answered not less than 75% of his bookish questions, so I was amused when the recruiter called after eight days saying my experience was not up to par. I have been rejected multiple times in phone interviews in the past and know how to take it in my stride, but this experience was unusual.

- 5.0An Engineer's Dream - Structure, Surveillance & Spreadsheets!Software Development Engineer In Test (SDET) • Former EmployeeChicago, Illinois, United StatesApril 10, 2025Pros: Rating: ⭐️⭐️⭐️⭐️⭐️ (Because who does not love being managed like a toddler?) Location: Groupon HQ (aka Productivity Palace) Review: If you are an engineer who thrives under constant supervision, then boy, do I have the place for you! At Groupon, I finally found the parental guidance I never knew I needed in my career. Micromanagement? Yes, please! Why be trusted to do your job when you can have the thrill of someone always peeking over your shoulder? It's like having a manager in your keyboard—a truly intimate experience. Jira tickets for every 4 hours? Brilliant! Who needs flow state when you can break your day into perfect little blocks of bureaucracy? Nothing screams "engineering excellence" like turning a coffee break into a documented artifact. Weekly Timesheets? Oh, the joy! Every Friday, I get to relive the week by reconstructing my every move. Did I spend 23 minutes debugging or 27? Let's debate! Bonus: it’s a great way to practice fiction writing. The 5/15 Rituals? Groupon has mastered the ancient art of status worship. What better way to grow as an engineer than by writing five updates a week about what I planned, did, didn’t do, and how I failed? It’s like Agile, but with extra steps and existential dread. Mandatory 3 days in office? Finally, a break from the horrors of home-cooked lunch and flexible hours! There’s nothing like braving traffic for some good old-fashioned chair warmth monitoring. It builds character (and carbon emissions)! In Conclusion: If you’re looking for a place where trust is earned every 4 hours, your life is fully auditable, and productivity is measured in Google Sheets, Groupon is the utopia you’ve been waiting for. Come for the code, stay for the KPIs.Cons: Management musical chairs—don’t get too attached to your manager; they’ll probably be gone by next quarter. You might start confusing your engineer role with part-time data entry, project manager, and bureaucratic monk.
