What is a 'problem statement' in a coding interview?
The problem statement describes the coding challenge: what the function should do, input and output types, constraints (size, time), and example inputs and outputs. Clarity here prevents misunderstanding.

What does 'clarifying question' mean in a coding interview context?
Clarifying questions from the candidate are a positive signal — they indicate problem-solving discipline. Encourage candidates to ask: 'Can the input array be empty?', 'Should I handle null values?', 'What is the expected time complexity?'

What is a 'hint' in coding interview facilitation?
Hints are calibrated prompts: 'Have you considered what data structure would give O(1) lookup?' Observing how a candidate responds to hints is valuable signal — strong candidates incorporate the hint and move forward effectively.

What does 'think out loud' mean in a coding interview?
Thinking aloud allows the interviewer to follow the candidate's reasoning — understanding their approach even if the code is imperfect. Prompt candidates who go quiet: 'Can you walk me through what you're thinking?'

What is 'time boxing' in coding interview facilitation?
Time boxing manages interview flow: signalling when to transition ('Let's move on, we have 5 minutes for discussion'), ensuring all areas are covered, and giving candidates a fair chance to complete each section.

Sarah from the frontend team is reviewing your PR for a new user registration flow. She comments: 'This validation logic feels a little brittle; what if we have different character sets in the username?' What does Sarah likely mean when she raises this concern?
Sarah is highlighting a design flaw – the code isn't robust enough to handle variations. 'Brittle logic' suggests a lack of adaptability and potential problems with future changes or different inputs. This is a common concern in code reviews focused on maintainability and anticipating edge cases.

David sends the following message in Slack: 'Hey team, just checking if anyone's seen the performance metrics for the new API endpoint. Response times are averaging 300ms – that's significantly higher than our target of 50ms.' What is David primarily trying to achieve with this message?
David's message clearly identifies a deviation from expected performance (300ms vs. 50ms) and frames it as an 'issue.' The language – 'significant,' 'higher than target' – signals urgency and the need for further scrutiny. It's not simply informing; it's raising a concern that warrants investigation.

You are writing the description for a pull request introducing a new feature to handle user profile updates. Which of the following best describes how to use the phrase 'As a developer, I want to…' in this context?
The 'As a developer, I want to…' format is a common technique in Agile development and user story writing. It focuses on the *value* being delivered – framing the feature from the user's perspective (even if the developer is implementing it). This helps stakeholders understand the purpose of the change.

During a standup meeting, Maria says: 'I'm working on integrating the new payment gateway. I've been battling with the API response format – it's incredibly inconsistent and changes frequently.' What is Maria most likely implying?
Maria's statement indicates a lack of clarity regarding the API. 'Inconsistent and changes frequently' suggests she's struggling to understand *how* to use it correctly – the core issue isn't necessarily with the documentation or the backend team's design, but her own comprehension.

Ben asks you during a code review: 'Can you explain your reasoning for using this particular algorithm here?' What does Ben likely want from you?
Ben isn't focused on whether the algorithm is technically correct or optimized. He wants to understand your *thought process* – why this particular solution was chosen. This demonstrates critical thinking and helps identify potential issues related to design choices that might not be immediately apparent.
