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

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

Onsite Interview Rounds

After clearing the technical virtual interview, 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 Qualis office.
