Submitting Your Application

The first step is to submit a compelling application that reflects your technical skills and interest in joining GoPro as a Machine Learning Engineer. Whether you were contacted by a GoPro 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.

Recruiter/Hiring Manager Call Screening

If your CV happens to be among the shortlisted few, a recruiter from the GoPro 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 GoPro Machine Learning Engineer 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.

Technical Virtual Interview

Successfully navigating the recruiter round will present you with an invitation for the technical screening round. Technical screening for the GoPro Machine Learning Engineer role usually is conducted through virtual means, including video conference and screen sharing. Questions in this 1-hour long interview stage may revolve around GoPro’s data systems, machine learning algorithms, data preprocessing, and model evaluation techniques.

In the case of machine learning roles, take-home assignments regarding modeling, data analysis, and algorithm optimization are incorporated. Apart from these, your proficiency against hypothesis testing, probability distributions, and advanced ML concepts 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.

Onsite Interview Rounds

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 throughout your day at the GoPro office. Your technical prowess, including programming, machine learning modeling capabilities, and problem-solving skills, will be evaluated against other candidates during these interviews.

If you were assigned take-home exercises, a presentation round may also await you during the onsite interview for the Machine Learning Engineer role at GoPro.
