Interviewing at Calico Life Sciences
Calico Life Sciences interviews you through a mix of recruiter or HR screens, manager and team interviews, and a research-facing presentation step. Across the roles covered in the data, Scientific/Technical Communication is a top topic, alongside Data Engineering and Python, so you should expect your ability to explain technical work clearly to be directly tested.
What gets tested is strongly weighted toward technical execution in data and engineering, plus domain-relevant scientific reasoning. The topic list includes Data Engineering, Data Pipeline Development, ETL, Data Analysis, Scalability, and Python at the highest prominence levels, and it also includes Scientific/Technical Interviewing and Research Seminar Delivery, which aligns with the research presentation step and technical communication focus.
There is also a noticeable conceptual and problem solving component that shows up across the technical topics. The topics list includes Machine Learning (concept), Problem Solving, and Data Pipeline Development plus Scalability, while the scientific side is reflected by PCR reaction components and PCR reaction fundamentals being among the most prominent topics. After interviews, candidate outcomes in the reports show an overall offer rate of 7.2%, with positive sentiment at 55.4%.
The most non-obvious part is that a research presentation is part of the process in the reported steps, and the topic coverage shows Scientific/Technical Communication and Research Seminar Delivery ranked at the top prominence levels. You should prepare to present research clearly, not just solve problems on paper.

The interview process, end to end
5 rounds · based on 83 candidate reports- 1Recruiter or HR screening and initial fit checks
You start with an HR or recruiter screen to discuss your background and motivations and to assess initial fit. Depending on the role path, you may see either a phone screen, a recruiter screening call, or an initial screening call.
- 2Application review
Your application is reviewed initially to assess qualifications and fit. This step is reported across roles covered in the data.
- 3Research presentation
You may present your past research in a seminar format to demonstrate communication skills. The reported duration for the research presentation is 30 to 60 minutes.
- 4Manager and cross-functional interviews
You move into interviews with hiring managers and cross-functional team members to evaluate communication skills and technical competencies and cultural fit. Some roles also include in-depth interviews and manager interviews as part of this phase.
- 5Final and onsite style interviews, plus any situational assessment
Some candidates go through final interviews described as comprehensive evaluations of communication skills and cultural fit, and one role has an onsite interview involving multiple rounds. A situational interview step is also reported for one role using situational questions and case studies.

Do this
- Prepare a seminar-style explanation of your past research that you can deliver in a 30 to 60 minute format, since the process explicitly includes a research presentation step. Focus on communicating decisions and tradeoffs, not only results.
- Be ready for Python and data engineering topics that appear at the highest prominence levels, including Data Pipeline Development and ETL. Practice outlining how you would extract, transform, load, validate, and monitor data flows.
- Cover scalability material because Scalability (system_design) is highly prominent in the topic list. Expect to discuss design choices that keep pipelines or systems reliable as data volume or workload grows.
- If the role you are interviewing for touches the scientific concepts in your space, review the PCR reaction components and PCR reaction fundamentals topics, since they are among the highest prominence items. Make sure you can explain the conceptual relationships clearly during technical discussions.
Avoid this
- Do not treat communication as secondary. Scientific/Technical Communication and Research Seminar Delivery are top prominence topics, and there is a research presentation step in the process.
- Do not focus only on general problem solving. Data Engineering, Pipeline Development, ETL, and Python are at the top of the prominence list, so a purely algorithmic approach will likely leave gaps.
- Do not ignore system-level thinking. Scalability is highly prominent, and the topic list includes system_design, so answers that only cover local fixes may not be enough.
- Do not assume the process is uniform across roles. The reported steps vary by role in the data, including onsite, in-depth interviews, and situational interviews, so be ready for different formats rather than a single fixed loop.
