Organizations actively use Salesforce to manage their customer data and interactions. However, the trouble with Salesforce is that it offers a wide range of products and services, including Sales Cloud, Service Cloud, and Marketing Cloud.

This makes it difficult for recruiters to understand the specific skills required for the role they are hiring and tailor questions accordingly.

Additionally, conducting Salesforce technical interviews can leave recruiters to tackle other crippling challenges, such as the inability to:

  • Screen job-fit candidates for the job vacancy
  • Drive an efficient screening process and technical evaluation
  • Access a pool of consistently engaging candidates
  • Measure the technical competencies of candidates
  • Evaluate the technical skills through live coding/programming interview assessment

To make things easier, we have listed 24 Salesforce technical interview questions recruiters can use and make their own.

Hiring managers can also look up iMocha's ready-to-use Salesforce skills test to hire qualified candidates in half the time (and effort).
