It seems like you're referring to a three-stage interview process that is commonly used by many companies when hiring candidates. Here's an overview of each stage: HR (Human Resources) Interview: The HR interview is usually the first step in the interview process. Its purpose is to assess your qualifications, experience, and basic compatibility with the company's culture and values. You may be asked about your resume, previous work experience, and your motivation for applying to the company. HR may also inquire about your salary expectations and availability. Technical Interview: The technical interview assesses your specific skills and knowledge related to the job you're applying for. Depending on the role, this could involve coding tests, technical questions, problem-solving exercises, or other job-specific assessments. Technical interviews are typically conducted by members of the team you'll be working with, such as engineers or subject matter experts. The depth and complexity of the technical interview questions will vary based on the role and the company. Managerial Interview: The managerial interview often takes place after the HR and technical interviews, especially for mid to senior-level roles. This stage assesses your ability to work within a team, manage people, and make strategic decisions. You may be asked about your leadership style, how you handle conflicts, and your approach to managing projects or teams. The interviewer may also inquire about your long-term career goals and how they align with the company's objectives. Each of these interview stages serves a specific purpose in evaluating your qualifications and fit for the job. It's important to prepare thoroughly for each stage and to research the company to understand its values and culture, as this information can help you tailor your responses to align with what the company is looking for in a candidate.
