Salesforce·Software Engineer·Onsite - Behavioral / Leadership

Apr 2026

Behavioral round at Salesforce for a full-stack role. Just the one question but they really sat with it, lots of follow-up probing on how I handled pushback.

Tell me about a time you had to convince a peer, manager, or stakeholder to adopt your approach. What was the situation, how did you make your case, what objections came up, and what happened?

“I went with a story about pushing for a different data-fetching strategy on a project where the team lead was pretty attached to the existing setup.”

Apr 2026

SQL-heavy technical screen for a full-stack role at Salesforce. Just one question but they really wanted to dig into the reasoning behind the approach, not just get a working query.

Given a users table and an orders table, write a SQL query returning all users who have never placed an order (user_id and name, ordered by user_id). Then walk through the trade-offs between LEFT JOIN with a NULL check, NOT EXISTS, and NOT IN.

“I went with LEFT JOIN first since that's what I reach for by default, and the query itself was fine.”

Apr 2026

Salesforce software engineer interview with a classic array problem. Nothing too wild, but the space constraint is where people trip up if they haven't seen it before.

Given an array of n distinct numbers covering the range [0, n] with exactly one value missing, find the missing number in O(n) time using O(1) extra space.

“The O(1) space requirement is the part that filters people out.”

Salesforce·Software Engineer·Onsite - System Design / Architecture

Apr 2026

System design round at Salesforce for a software engineer role, focused entirely on building a rate limiter for a high-cost API with user-configurable monthly quotas. Pretty deep dive, they wanted real tradeoffs not just buzzwords.

Design a rate limiter for an expensive API where each user can configure their own monthly quota. Walk through where the limiter lives, which algorithm you'd use and why, how you track and reset monthly usage, your storage choices, concurrency correctness, mid-month quota changes, failure behavior, and how you communicate limits back to clients.

“This is basically one big question with seven sub-questions inside it.”

Salesforce·Software Engineer·Technical Phone Screen

Apr 2026

Salesforce frontend interview that was basically a currying deep-dive disguised as a simple addition function. Starts innocent enough and then they just keep pulling the thread.

Implement an `addTwoNumbers` function in JavaScript using currying so it can be called as `add(a)(b)` and returns `a + b`.
Extend the curried function to support any number of chained calls, like `add(a)(b)(c)...`, where the final value is returned either via `valueOf` or by calling with no arguments.
How would you handle non-number arguments passed into the curried add function?
Explain how closures work in the context of this function and how the accumulated state is maintained across calls.

“The basic version is fine, you write a function that returns a function and done.”

Salesforce·Software Engineer·Technical Phone Screen

Apr 2026

Salesforce coding screen with one array problem that looks straightforward but has a few edge cases worth thinking through carefully.

Given an integer array, for each index produce two binary strings: one marking whether the element has appeared before that index, and one marking whether it appears again after that index. Return both strings.

“Pretty clean problem once you realize it's just two passes and a frequency map.”

Salesforce·Software Engineer·Hiring Manager Screen

Apr 2026

Interviewed for a sales rep role at Salesforce. One round, pretty conversational, mostly about how you handle objections in the field.

A customer pushes back on your product's price and asks why it costs so much. How do you handle that?

“I went straight to value justification, ROI, total cost of ownership, the usual.”

Salesforce·Software Engineer·Technical Phone Screen

Apr 2026

Salesforce coding interview, got hit with the LFU cache design problem. Not the worst session I've had but definitely not a gimme either.

Design and implement an LFU (Least Frequently Used) cache class with get and put operations, both running in O(1) average time. On eviction, remove the least frequently used key, and break ties by removing the least recently used among those.

“I knew LRU cold but LFU is a different beast.”

Salesforce·Product Manager·Onsite - Product Sense / Strategy

Apr 2026

PM interview at Salesforce with a product design question that felt deceptively simple but had a lot of hidden depth once I started talking through it.

Design a bookshelf specifically for children.

“I jumped straight into features and kind of skipped the user framing entirely.”

Salesforce·Software Engineer·Technical Phone Screen

Apr 2026

Salesforce full-stack screen, pretty SQL-heavy. One question but they really dug into the edges of it, not just 'write the query and move on'.

Given a users table and a transactions table, write a SQL query to find all users who have never made a transaction. Then walk through the trade-offs between LEFT JOIN with a NULL check, NOT EXISTS, and NOT IN, including why NOT IN can behave unexpectedly with NULLs.

“Got the LEFT JOIN version out fast, felt good about it.”
