Coding Technical
Got into the company via Hired, and it was super professional, nice people. First, a quick HR call that felt more like a marketing chat. Then, a 45-minute Zoom tech screen with one frontend dev, who seemed to be from a BootCamp and focused on coding, and the Executive Developer. They were cool about me not knowing the ES6 answers immediately, as the role is specifically for a Senior ES6 Developer. It would have been helpful to know the tech stack details upfront.

Coding Technical Behavioral
This was my first interview experience that felt really personal, not like the usual generic ones. After a chat with HR, the first step was an algorithm challenge. I liked how they gave me a small algorithm and then asked me to expand on it, which really tested my JavaScript abilities and was spot-on for the role. Then came the onsite interviews where I met the engineers I'd be collaborating with and some senior folks. The onsite included discussing my experience and a coding session using React. This was also very relevant to the job. Everyone I met was super friendly and made me feel welcome. I genuinely enjoyed the whole process and getting to know the team.

Coding Behavioral
This was the worst interview experience ever. The onsite interview was only 2.5 hours long, with 30 minutes spent on HR stuff like start dates and salary. The remaining two hours had two coding parts. The first was to build a React component and then add debouncing. The second coding part was about using JS promises in weird ways. These tests don't seem like enough to judge someone unless they completely fail at basic coding. Also, three out of the four engineers were rude or seemed bored. One guy just scowled the whole time. I got rejected less than an hour after it ended.
