In the case of data engineer roles, take-home assignments regarding data model architecture, ETL processes, and data governance may be incorporated. Apart from these, your proficiency in cloud services such as AWS, Snowflake, and Python or JavaScript 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 will be conducted during your day at the Indigo office. Your technical prowess, including programming, data modeling, and system design capabilities, will be evaluated against the finalized candidates throughout these interviews.
