Went through the use cases and they pushed back hard, like the whole thing was a waste of time.
Start with a high-level summary of your product, then explain the specific user or business problem it solves and why existing alternatives fall short. Use concrete evidence like user metrics or market trends to justify its necessity, and connect it to the company's strategic goals.
Pro tip: Emphasize the 'why now' — what changed in technology, user behavior, or the market that makes this product essential today. Also, subtly tie the product's value to AT&T's broader mission (e.g., connectivity, 5G, customer experience) to show alignment.
Give a concise, jargon-free description of your product: what it does, who it's for, and its core value proposition.
Clearly state the specific pain point or unmet need your product addresses, using data or user feedback to validate it.
Explain how current alternatives (competitors, manual processes, legacy systems) fail to fully solve the problem, highlighting gaps your product fills.
Provide quantitative or qualitative proof that the product is needed, such as adoption rates, user retention, revenue impact, or market demand.
Connect the product's necessity to broader business goals or industry trends, especially those relevant to AT&T (e.g., 5G, IoT, customer experience).

Restate the problem in your own words to confirm understanding, then walk through a simple example to clarify edge cases. Discuss a brute-force solution first, then optimize using appropriate data structures or algorithms, explaining trade-offs. Code the optimized solution while narrating your thought process, and finally test with the example and edge cases.
Pro tip: Before coding, ask clarifying questions about input constraints (e.g., size, range, duplicates) to demonstrate thoroughness and adaptability. This also helps you choose the right approach and shows you think about real-world scenarios.
Restate the problem and ask clarifying questions about input constraints, expected output, and edge cases. This ensures you solve the right problem and shows attention to detail.
Walk through a simple example and a tricky edge case to solidify your understanding and identify patterns. This helps you catch misunderstandings early.
Start with a brute-force solution, then propose an optimized approach using appropriate data structures or algorithms. Explain time and space complexity trade-offs.
Write clean, modular code while explaining each step. Use meaningful variable names and handle edge cases as you go.
Run through the example and edge cases, checking for off-by-one errors and boundary conditions. If time permits, discuss potential improvements or alternative solutions.
