Strive Health is a mission-driven organization focused on revolutionizing kidney care. By leveraging advanced data analytics and a high-touch care team, Strive Health identifies and engages at-risk kidney disease patients, enhancing their care journey from chronic kidney disease to end-stage kidney disease. The company's innovative approach significantly reduces emergent dialysis and inpatient utilization while improving patient outcomes.
As a Senior Data Scientist at Strive Health, you will be integral to this mission, defining machine learning roadmaps, building ML models, and collaborating with cross-functional teams to integrate these models into clinical workflows. This role demands strong technical expertise, including knowledge of ML frameworks, cloud environments, and statistical modeling. With a competitive compensation package and numerous wellbeing and professional development benefits, Strive Health is an excellent place for top talent in healthcare to thrive.
The first step is to submit a compelling application that reflects your technical skills and interest in joining Strive Health as a Senior Data Scientist. Whether you were contacted by a Strive Health recruiter or have taken the initiative yourself, carefully review the job description and tailor your CV according to the prerequisites.
Tailoring your CV may include identifying specific keywords that the hiring manager might use to filter resumes and crafting a targeted cover letter. Furthermore, don’t forget to highlight relevant skills and mention your work experiences.
If your CV happens to be among the shortlisted few, a recruiter from the Strive Health Talent Acquisition Team will make contact and verify key details like your experiences and skill level. Behavioral questions may also be a part of the screening process.
In some cases, the Strive Health data scientist hiring manager may be present during the screening round to answer your queries about the role and the company itself. They may also indulge in surface-level technical and behavioral discussions.
The whole recruiter call should take about 30 minutes.
Successfully navigating the recruiter round will present you with an invitation for the technical screening round. Technical screening for the Strive Health Senior Data Scientist role usually is conducted through virtual means, including video conference and screen sharing. Questions in this 1-hour long interview stage may revolve around data systems, ETL pipelines, and SQL queries.
In the case of data scientist roles, take-home assignments regarding product metrics, analytics, and data visualization are incorporated. Apart from these, your proficiency against hypothesis testing, probability distributions, and machine learning fundamentals may also be assessed during the round.
Depending on the seniority of the position, case studies and similar real-scenario problems may also be assigned.
Followed by a second recruiter call outlining the next stage, you’ll be invited to attend the onsite interview loop. Multiple interview rounds, varying with the role, will be conducted during your day at the Strive Health office. Your technical prowess, including programming and ML modeling capabilities, will be evaluated against the finalized candidates throughout these interviews.
If you were assigned take-home exercises, a presentation round may also await you during the onsite interview for the Senior Data Scientist role at Strive Health.
