Problem Statement:
Design backend service, when user tries to signup two operations to be performed.

1. Perform KYC checks (third party service) as first step and store the results in database before going to next step.
2. Perform user registration checks (third party service) as second step and update the results done in step1

User should be able to resume from step2 if step1 is successful.

I was rejected because I chose complex solution straightway.

any tips on how to approach this or any design solution? Thanks
