Behavioral Technical Coding System Design
The whole thing took about 5 weeks, with several rounds. It was cool talking with the team, and the questions were pretty standard for a senior role, they made it fun. I did a live coding thing in 10 seconds, which impressed the interviewer. The final architecture discussion went well too, gave me a feel for their tech vision. Didn't get an offer though. Not sure why, maybe it was compensation because the budget changed and ended up being lower than expected for senior. Still, I liked the team and company and would consider them again.

Behavioral Technical Coding Presentation
The application process was a bit out there, starting with questions about SAT scores and essays. Then there was a 12-minute cognitive test with 50 questions. Instead of a typical coding test, they emailed a PDF with starter code and expected the completed code back within a set time. After that, I had a behavioral interview where I noticed some red flags. When I asked about working during the pandemic, they focused only on sales declining, not employee impact. They were vague about training, saying they 'throw you in to the deep end.' The final interview was a video call with mostly men, and one senior person was quite rude. When asked about other offers, I said yes, and he called my other offer a 'cushy 9 to 5' and implied I might need to take a salary hit if the company faced issues, questioning my drive. This felt like a sign of an unstructured company that doesn't value work-life balance.

Behavioral Technical Coding
The interview process was pretty laid back and open. I started with the CTO, and then two developers joined in. They asked some brief, guiding questions, then really dug into topics like microservices, data modeling, and even my work ethic and motivations. They seemed genuinely interested in my background and what I could contribute. They were also open about the team's current situation. While I didn't have a coding test, they did put me on the spot to talk through three Javascript exercises that clearly aimed to highlight some tricky language details. I think I did alright on those.

“Given that Michael is quicker than Henry, and Alan is quicker than Michael, does this mean Alan is quicker than Henry?”

The goal is to remove characters from consecutive runs if the run length exceeds `maxRepeat`, similar to these examples: with 'xxxy' and a maxRepeat of 2, the result is 'xxy'; with 'xxyy' and a maxRepeat of 1, the result is 'xy'; and with 'xxxxyyyyxx' and a maxRepeat of 1, the result is 'xyx'.”

The pricing methods include Daily, Hourly, and Distance (per mile), and vehicle types include Charter Bus, Mini Bus, Sprinter, Party Bus, Sedan, SUV, Limousine, and Trolley.
