The interview process at Gong consists of several structured steps:

• It begins with a call from a Talent Acquisition representative.
• This is followed by an initial technical screening that includes a “tell me about yourself” segment.
• Next is an on-site technical interview with the hiring manager, focused on two design questions.
• A take-home assignment involving Java Spring Boot development in the calendar domain follows.

Candidates should prepare thoroughly by sharpening their Java skills, gaining in-depth knowledge of Spring Boot (including understanding annotations, exception handling, OOP, OOD, and testing methodologies), and practicing algorithmic problem-solving.

A code review session follows, during which you present your assignment and answer questions. This is succeeded by an interview with the group lead and a final one with HR.

Overall, the process is manageable for senior-level engineers, as the focus is more on practical knowledge of Java, Spring Boot, and writing production-grade code rather than cutting-edge technologies.

Communication with the team is solid, but the technical depth of the interviewers may not align with expectations. It’s important to clearly understand Gong’s current position, your potential role within the team, and what will be expected of you.
