Perguntas de entrevista da empresa Exponential AI

I applied online through the company’s careers page. I was contacted within a week by a recruiter for an initial phone screen. The recruiter was friendly and asked basic questions about my background, experience, and interest in the role. Step 1: Phone Screen (30 minutes) The recruiter asked about my resume, technical background, and why I was interested in the company. There were also a few basic behavioral questions. Step 2: Technical Interview (1 hour) This round was conducted via Zoom with a hiring manager or engineer. I was asked to solve a coding problem using [language or tool used], and then discuss my thought process. The interviewer was supportive and gave hints when needed. Step 3: Final Round / Onsite (2–3 hours) This round consisted of multiple back-to-back interviews with different team members. It included a mix of technical problems, system design, and behavioral questions. I was also given a chance to ask them questions about team culture and the role.
