- SalesforceMediumSoftware EngineerBehavioral: Coaching a Teammate and Upholding Team Coding Standards
Two-part behavioral question for senior engineers: how you helped a teammate get better at a specific task, and how you maintain coding standards across your team. It tests mentoring approach, measurable growth, automating standards, code review norms and building team buy-in.
Behavioral & LeadershipOther - SalesforceMediumSoftware EngineerBehavioral: Pivoting Mid-Project and Handing Off Work You Owned
Two-part behavioral question for senior engineers: a time you had to pivot in the middle of a project, and a time you were pulled off a project where you were the main point of contact. It tests adaptability, re-planning, stakeholder communication and responsible handoffs.
Behavioral & LeadershipOther - SalesforceMediumSoftware EngineerCount the Steps at Which Set Bits Form an Exact Prefix of Ones
Array problem: the bits of an all-zero binary string are set one at a time in the order given by a permutation; count the steps after which exactly the first i bits are set. It tests careful reasoning about prefix conditions and handling large inputs efficiently.
Coding & AlgorithmsOther - SalesforceMediumSoftware EngineerDelete Every Value That Repeats in an Unsorted Singly Linked List
Linked list problem: delete every node whose value occurs more than once in an unsorted singly linked list, removing all copies and keeping the remaining nodes in their original order. It tests frequency counting, list traversal and careful handling of removals, including at the head of the list.
Coding & AlgorithmsOther - SalesforceMediumSoftware EngineerDesign a tenant-isolated system to replicate large recordings to per-customer data centers
System design question: build a tenant-isolated pipeline that copies large files such as call recordings from a source data center to each customer's chosen data centers. It tests staged design from a simple copy to asynchronous fan-out, resumable transfers, retries, verification, reconciliation and per-tenant isolation.
System DesignOther - SalesforceMediumSoftware EngineerMulti-tenant resource allocator: entity model, lifecycle state machine, optimistic locking
Low-level design question for a senior backend role: model a multi-tenant resource allocation module where customers request and release resources. It tests compact class design, an explicit resource lifecycle state machine, optimistic locking under concurrent requests, and tenant isolation enforced in code.
Software Engineering FundamentalsOther - StripeMediumSoftware EngineerArchitecture Deep-Dive: 15–20 Minute Past-Project Talk and Retrospective Follow-ups
A Stripe staff-level architecture deep-dive: present a past technical project in 15 to 20 minutes, then field follow-ups such as what you would do differently. It assesses technical depth, how clearly you explain key design decisions and rejected alternatives, credible ownership of the work, and honest retrospection.
Behavioral & LeadershipOther - StripeMediumSoftware EngineerReview a Production Pull Request and Calibrate Feedback to the Author's Seniority
A staff-level Stripe code review exercise: review a realistic production pull request, decide what blocks the merge, and write the actual comments. It tests review prioritization, scrutiny of tests and failure modes, comment severity labeling, and how you adapt the delivery of feedback for early-career versus senior authors.

Stripe staff-level behavioral prompts covering a difficult technical decision made with incomplete information, aligning stakeholders with competing goals, and mentoring engineers while scaling your technical influence. It evaluates judgment under uncertainty, influence without authority, and concise, impact-first storytelling.
Behavioral & LeadershipOther - VisaMediumSoftware EngineerBehavioral: Solving a Hard Problem Simply and Breaking a Complex Project Into Parts
Two senior behavioral prompts about complexity: describe a hard problem you solved with a simple solution, and a time you split a complex project into manageable parts. They probe judgment about simplicity, handling ambiguity, decomposition and sequencing, personal ownership, and measurable results.
