Behavioral Technical Coding
The interview process involved six stages: a basic fit interview, a cognitive aptitude test, a complex problem-solving assessment, and then a series of specialized interviews focused on AI augmented defect resolution and AI augmented feature development. The interviewer was quite rude, only knowing JAVA and expecting me to be an expert in everything he knew.

- Can you share how you've utilized AI?
- You're given a backend system that fetches data from user and post tables. It's experiencing performance issues in production, traced to this specific code: async function getUsersWithPostCountAndEarliestPostDate() { const users = await db.query('SELECT u.id AS user_id, u.name AS user_name FROM users'); for (let user of users) { const posts = await db.query('SELECT * FROM posts WHERE user_id = ?', [user.id]); user.post_count = posts.length; user.earliest_post_date = posts.reduce((earliest, post) => post.created_at < earliest ? post.created_at : earliest, Infinity); if (user.earliest_post_date === Infinity) { user.earliest_post_date = null; } } return users; }. What's the issue with this code, and how would you fix it?
- Write code for a tree.

Technical Coding
Most jobs require 4+ hours of testing to even be considered for a position, most of which is driven by time consuming tests, and the dumbest AI interviewer I have had the displeasure of working with, as it forgets previous answers or gets on a tangent of unanswerable questions always asking for more detail even if you answer "refer to my prior answer" or "I have no experience with [Process], but I have experience with [Another similar process]". There were multiple times where the AI Interviewer refuses to start and you watch the "I'm thinking" three dots for an hour, unable to type or end the interview early to try again. The AI must be learning from real recruiters as it ghosted me during an interview.

- Can you tell me about your knowledge of SQL and its various forms?
- What can you tell me about your experience with other data tools?
