Hi Steve,
Thank you for contacting Syncfusion support.
Though this query is not related to any of our EJ2 components, we can only share our general insights about the interview process since we are not able to comment on any online certification courses in our forum.
The certificates that we include to our resumes only give mere list of our skills to the interviewer but the way we express our comfortability/expertise while responding to challenges/queries in interview will matters in cracking the interview.
Regards,
Jesus Arockia Sankaran S
