Interviewing at Moderna
At Moderna, your loop can involve both HR and panel formats. Reported formats include a comprehensive panel lasting around 3.5 hours with a research seminar followed by one-on-one or small-group interviews, plus back-to-back interviews with multiple team members to assess both technical depth and cultural fit.
Across the roles we have guides for, the questions consistently emphasize practical technical skills and communication. The interview topic list shows very prominent focus on Python, JavaScript concepts, SQL, technical interview questions, and coding or problem solving, alongside behavioral interviewing using STAR, and in-depth domain research communication presented as a seminar/presentation.
The data also shows online testing and structured screening steps. You may see an HR screening call or initial screening discussion with a recruiter, plus online assessments such as technical competencies, optional cognitive or logic tasks, and online behavioral assessment to evaluate work style and decision-making.
You should expect you will be asked to communicate research or domain thinking, not just solve problems. The interview topic list is strongest on scientific seminar or presentation and in-depth domain research communication, and the reported panel format explicitly includes a research seminar.

Do this
- Prepare to explain your domain or research work like a seminar. The process and topics data both point to scientific seminar/presentation and in-depth domain research communication as central themes.
- Practice SQL and Python, and be ready to apply them in technical questions rather than just reciting syntax. SQL has a very high percentile, and Python is also at the top of the topic distribution.
- Use STAR structure for behavioral questions tied to technical skills and communication. Behavioral interviewing with STAR is listed at the top percentile, so rehearse specific, outcome-focused stories.
- Be ready for panel style follow-ups and concise technical alignment. The reported comprehensive panel format uses multiple stakeholders and often includes one-on-one or small-group segments.
Avoid this
- Do not assume the interview is only coding. The topic list is heavy on Python, SQL, JavaScript concepts, and technical interview questions, but also includes project management, communication, and research presentation.
- Avoid speaking without clear decision-making structure. The data includes online behavioral assessment and behavioral interviews, so practice explaining how you reached decisions and what you changed based on feedback.
- Do not ignore communication of domain research, even if your role is technical. Scientific seminar/presentation and in-depth domain research communication are both highest prominence topics.
- Do not treat assessment steps as optional in your prep plan. Reported online assessments and screening steps include technical competencies, and there is also an online behavioral assessment.
