The interview process for a Software Engineer at PathAI is structured to assess both technical skills and cultural fit within the team. It typically unfolds over several stages, allowing candidates to showcase their abilities and learn more about the company.

1. Initial Recruiter Screen

The process begins with a phone call from a recruiter, lasting about 30 minutes. This initial screen focuses on basic qualifications, your interest in the role, and an assessment of cultural fit. The recruiter will likely ask about your background, experience, and motivations for wanting to join PathAI.

2. Online Assessment

Following the recruiter screen, candidates are usually required to complete an online assessment, often hosted on HackerRank. This assessment typically consists of multiple coding questions that test your problem-solving skills and understanding of algorithms and data structures. The duration of this assessment can vary, but candidates should expect to spend around 60 to 180 minutes on it, depending on the complexity of the questions.

3. Technical Interviews

Successful candidates from the online assessment will move on to a series of technical interviews. These interviews usually consist of two to three rounds, each lasting approximately 45 minutes. During these sessions, candidates will engage with engineers and product leaders, tackling coding challenges in real-time, discussing system design, and demonstrating their proficiency in Python and relevant frameworks like Django or FastAPI. Expect to solve problems collaboratively, as pair programming may be a component of this stage.
