Recruiter/Hiring Manager Call Screening

If your CV is shortlisted, a recruiter from the Amtex Systems Talent Acquisition Team will contact you to verify your experiences and skill levels. Behavioral questions may also be 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 engage in surface-level technical and behavioral discussions.

The whole recruiter call should take about 30 minutes.

Technical Virtual Interview

Successfully navigating the recruiter round will present you with an invitation for the technical screening round. Technical screening for the Data Scientist role at Amtex Systems Inc. is usually conducted through virtual means, including video conferences and screen sharing. Questions in this 1-hour-long interview stage may revolve around data systems, machine learning pipelines, and SQL queries.

Given the nature of the role, take-home assignments involving data visualization, statistical analysis, and machine learning problem-solving may also be incorporated. Your proficiency in machine learning algorithms and frameworks (such as TensorFlow, PyTorch, and Scikit-learn) as well as your familiarity with DevOps tools (like Docker and Kubernetes) may be assessed during this round.

Depending on the seniority of the position, case studies and similar real-scenario problems may also be assigned.

Onsite Interview Rounds

After a second recruiter call outlining the next stages, you’ll be invited to attend the onsite interview loop. Multiple rounds, including technical and behavioral interviews, will be conducted during your day at the Amtex Systems office or virtually if the position is remote. 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.
