If you're a seasoned professional with experience in software design, data modeling, and statistical analysis, this could be your next exciting challenge. Our ideal candidate has a background in government procurement, AML investigations, and knowledge of the Microsoft Azure ecosystem. In this guide from Interview Query, we’ll navigate you through the interview process, offer insights, and share valuable tips to help you succeed.
Let's get started!
The first step is to submit a compelling application that reflects your technical skills and interest in joining Techstar Group as a Data Scientist. 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. Don't forget to highlight relevant skills and mention your work experiences, particularly those related to software design, AI, and ML technologies.
If your CV happens to be among the shortlisted few, a recruiter from the Techstar Group 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 hiring manager stays 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 Techstar Group 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 AI technologies, machine learning solutions (e.g., classification, regression, clustering), and programming in languages such as Python, T-SQL, or R.
In addition to this, your proficiency in hypothesis testing, probability distributions, and the Microsoft toolset in AI and ML (e.g., Azure Machine Learning, Azure Cognitive Services) 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 will be conducted during your day at the Techstar Group 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 Data Scientist role at Techstar Group.
