Salesforce Software Engineer Interview Questions

I would separate task submission from execution so work can be buffered and processed reliably. Then I would make the processor idempotent and add retry handling for failures. That gives a system that can survive spikes and partial outages.

I would measure what is slow, reduce unnecessary network calls, and cache or precompute expensive data where possible. Then I would verify that any change improves the real user experience rather than just a benchmark. Strong performance work starts with evidence.

I would index the important fields, support filtering and relevance ranking, and keep the query path fast enough for interactive use. Then I would think about freshness, pagination, and scaling as the dataset grows. Good search is useful because it returns the right answer quickly.

I would cover the main logic with unit tests, validate integrations with end-to-end or integration tests, and exercise failure paths where it matters. Then I would check observability so issues are visible after launch. Good testing reduces surprises without slowing the team too much.

I would make sure the system has useful logs, metrics, and traces so problems can be diagnosed quickly. Then I would define the signals that matter most for user impact and service health. Good observability turns production from a black box into something understandable.
