Our Recruitment Process

Thank you for your interest in joining the Natterbox team. We believe in transparency, structured feedback, and human-centred communication. Below is a clear outline of what you can expect during your candidate journey with us.

Our Communication Commitment

We respect the time and effort it takes to submit an application. All applicants will receive a response from us.

Please note: Due to the high volume of applications we receive, we are unfortunately unable to provide individual, personalised feedback at the initial CV review stage.

Stage 1: Initial CV Review

Our People Team carefully reviews every CV against the core competencies and technical requirements of the role.

Stage 2: People Team Interview (30 Minutes)

If your application matches our criteria, you will be invited to a 30-minute introductory call with a member of our People Team.

• What to expect: This is a two-way conversation to review your CV, discuss your background, and talk through how your skills and experience align with the role.

Stage 3: Department Head Interview

Candidates progressing to the next round will have a focused call with the Department Head.

• What to expect: A deeper discussion into the practical, day-to-day elements of the role, your technical diagnostics approach, and how you tackle customer support challenges.

Stage 4: Team Leader Panel Interview

You will then meet our team leaders for a structured panel interview.

• What to expect: This stage will focus on scenario-based questions

Stage 5: Final Executive Review

The final stage is a call with a member of our Executive Team.

Important Note on the Use of Artificial Intelligence (AI)

We encourage our candidates to embrace modern tools and work smart.

• What is acceptable: It is completely fine to use generative AI (such as ChatGPT, Gemini, or spelling/grammar assistants) to help refine, format, or polish your CV structure and application answers.
• What is not acceptable: We strictly ask that you do not use AI to generate or write answers on your behalf.

We value authenticity, genuine communication, and real problem-solving. Our multi-stage interview process is designed to deeply assess your individual skills and unique technical approach. Relying on AI to answer on your behalf during the application stages creates a disconnect during live conversations, and ultimately prevents us from getting to know the real you. Please ensure all submitted answers reflect your own words and honest experience.
