Faire·Software Engineer·Technical Phone Screen

Jun 2026
Faire SWE interview with a Pascal's triangle formatting problem. More of a math-meets-implementation puzzle than a pure algo question, which I wasn't expecting.
  • Given a positive integer representing the height of Pascal's triangle, generate the triangle and print it as centered text. Each number should be right-aligned in a field width equal to the digit count of the largest value in the triangle, and each row should be visually centered relative to the widest row.

“The actual triangle generation was fine, that part I knew cold.”

Faire·Software Engineer·Onsite - System Design / Architecture

Jun 2026
System design round at Faire for a software engineer role. The whole thing was basically one API design question that went deeper than I expected.
  • Design an HTTP API that generates Pascal's triangle up to a given height. The server returns raw numeric data only; the client handles all formatting and display. Walk through the endpoint design, request parameters, response schema, validation, error handling, and any limits you'd impose.

“Seemed simple at first and I kind of rushed into talking about the math before realizing they wanted the full API contract, not an algorithm.”

Faire·Software Engineer·Onsite - System Design / Architecture

Jun 2026
Faire SWE interview that started as a coding problem and then pivoted into a full API design discussion around the same Pascal's Triangle idea. Interesting format, felt more like a design conversation than a standard interview.
  • You've implemented Pascal's Triangle as a coding exercise. Now design the API that a service would expose to clients for retrieving it.
  • Should the server handle formatting and rendering of the triangle, or should that be the client's responsibility? Justify your choice.
  • How would you handle very large triangle heights, including caching, pagination, and big integer values in the response?

“The pivot from coding to API design threw me a bit.”

Jun 2026
Faire SWE interview had a string manipulation problem that looks like a known LeetCode question but isn't, and that gap will catch you if you're not careful.
  • Split a long message into chunks of a bounded length, but you can only cut at word boundaries. Splitting mid-word is not allowed, and the output chunks may have leading or trailing spaces.

“I recognized the structure immediately and started coding toward a solution I'd seen before.”

Faire·Software Engineer·Onsite - Behavioral / Leadership

May 2026
Behavioral round at Faire for a software engineering role. The interviewer read every question straight off a script, which made the whole thing feel weirdly stiff, like a DMV appointment.
  • Tell me about a time you disagreed with your team's decision. How did you handle it?

“The interviewer literally read this off a sheet, which threw me a little.”

Faire·Software Engineer·Onsite - System Design / Architecture

May 2026
Did a system design round at Faire for a software engineer role and got rejected because my solution was apparently too complicated. Came in with a data infra background and thought that would work in my favor. It did not.
  • Design a 'like' system for brands. Cover the high-level design, API, data model, and how you'd scale it.

“I went pretty deep here.”

May 2026
Faire SWE interview had me implementing Pascal's Triangle with a specific symmetric formatting requirement. The logic itself wasn't too bad but the display math took longer than I expected.
  • Implement Pascal's Triangle for a given height, printing each row so the overall triangle appears visually centered and symmetric. The formatting requires right-padding every number to the width of the largest number in the triangle, using that same width as the gap between adjacent numbers, and indenting each row to center it.

“The actual value generation was fine, standard row-by-row accumulation.”

Faire·Software Engineer·Technical Phone Screen

May 2026
Coding screen at Faire for a software engineering role. The problem looked deceptively simple on the surface but turned into a messy whitespace edge case marathon. No clean algorithm, just a pile of conditionals.
  • Given a space-separated message string and a per-line character limit, split the message into lines where each line includes a numbered suffix (like #01) that counts toward the character limit. Handle whitespace carefully: no trailing space on the last line, and whitespace between the message content and the suffix can be dropped and pushed to the next line instead.

“I kept thinking there was some elegant solution hiding in there but there really isn't.”

Faire·Backend Engineer·Technical Phone Screen

May 2026
Faire backend interview with a line sweep problem that sounds easy until you actually have to defend your approach against alternatives. One question, but the discussion part was where they really dug in.
  • Given a list of events each with a start time, end time, and a capacity value, find the maximum total capacity required at any single point in time across all overlapping events.

“I went for a heap-based interval approach first because that's what my brain defaults to for overlap problems.”

Faire·Software Engineer·Technical Phone Screen

Apr 2026
Faire coding interview for a software engineer role. One meaty algorithm question with a bunch of follow-ups baked in. The problem looked like a fun puzzle at first glance but the edge cases piled up fast.
  • Given a sentence with mixed casing and punctuation, and a dictionary mapping lowercase words to syllable counts, write a function that finds and returns the first valid haiku (5-7-5 syllable structure) as three lines formed from a contiguous sequence of words in the sentence. Return null if none exists. Discuss your approach, complexity, and edge cases like unknown words, apostrophes, and irregular spacing.

“I started with a sliding window idea and then they nudged me toward prefix sums which honestly made more sense once I drew it out.”
