Overview of Ionic Interview Process
The Ionic interview process is designed to assess the technical and professional abilities of a potential applicant. It typically consists of a phone interview, a technical interview, and a behavioural interview.
The phone interview is used to determine the applicant’s basic technical skills and basic understanding of the Ionic platform. The interviewer will ask general questions about the candidate’s background and experience in the Ionic framework, as well as basic questions about the platform itself. The phone interview is typically conducted by an engineer from the Ionic team.
The technical interview is used to determine the applicant’s more advanced knowledge of the Ionic platform. The interviewer will ask questions about specific Ionic components, such as the CLI and Cordova plugins, as well as more general questions about mobile development. The technical interview is typically conducted by a senior engineer from the Ionic team.
The behavioural interview is used to assess the applicant’s soft skills, such as their ability to work in a team, their ability to problem solve, and their communication skills. The interviewer will ask questions about the applicant’s past experiences and how they have handled difficult situations. The behavioural interview is typically conducted by a person from the human resources department.
The Ionic interview process can be quite rigorous, but it is designed to ensure that the successful applicant will be an asset to the team. By the end of the process, the interviewer should have a clear picture of the applicant’s technical and professional abilities.
