Salesforce Software Engineer Interview Questions

1.Tell me about a specific time you dropped what you were doing to help a teammate who was struggling or stuck. What was the situation and what did you sacrifice to help them?

2.Walk me through a time you used your technical skills for a cause or community project outside of work. What was the impact?

3.Describe a technical problem you'd solved before, but then realized there was a completely different approach. What made you reconsider your original solution?

4.Describe the last time you noticed a colleague was overwhelmed or burning out. What specific actions did you take, and how did you know it made a difference?

5.Tell me about a project where you had to make a decision that disappointed one group to benefit another. How did you approach that tradeoff?

6.Tell me about a time you questioned an established process or tool your team had been using for months. What made you think there was a better way, and what happened next?

7.You're working on Sales Cloud and need to implement a feature that lets users bulk update 10,000 opportunity records. The current API times out at 2,000 records. How would you design this to handle the scale?

8.Our Lightning Web Component is making 15 different API calls when a user opens the opportunity detail page. Users are complaining it's slow. Walk me through how you'd optimize this.

9.You're building a microservice that needs to send notification events to Slack when opportunity stages change in Sales Cloud. The service handles 50,000 stage changes per minute during peak hours. What's your approach?

10.A customer reports that their Einstein AI lead scoring is giving different results for the same lead data when called multiple times. The model was retrained last week. How do you debug this?

11.Your team needs to migrate 100TB of customer data from our legacy PostgreSQL cluster to the new Data Cloud infrastructure. The migration must complete with zero downtime and data consistency guarantees. Design your approach.

12.You're implementing a real-time collaboration feature for Slack where multiple users can edit the same document simultaneously. The document can have 10,000+ concurrent editors. Walk me through your technical design.

13.Design a feature flag service for Einstein AI that can determine which model version to serve for each customer's predictions. It needs to handle 500,000 requests per second and support gradual rollouts.

14.You're designing MuleSoft's API analytics platform that tracks usage patterns across 100,000+ customer APIs. The system must detect anomalies in real-time and provide detailed usage reports without impacting API performance.

16.Design the backend system for Slack's workflow automation that integrates with Salesforce objects. When a deal closes in Sales Cloud, it should trigger complex multi-step workflows across different Slack channels and potentially update Service Cloud cases.

25.Estimate how many API calls Sales Cloud receives per day across all our customers. Walk me through your reasoning and key assumptions.

26.MuleSoft's API marketplace shows that 40% of our integration templates haven't been downloaded in 6 months. How would you investigate whether we should deprecate them or improve discoverability?

27.Service Cloud agents are reporting that Einstein Case Classification is suggesting the wrong categories 30% of the time, up from 15% last month. How would you investigate this regression?

28.Estimate the storage cost impact if we decided to keep all Slack message history forever instead of our current retention policies. What are the key cost drivers?

29.A Tableau dashboard showing quarterly sales performance is loading slowly for our largest enterprise customer. Their dataset has 50 million rows. How would you diagnose and solve this performance issue?
