Application engineer interview questions, and what each one tests

Originally published on four-leaf.ai . Application engineer interview questions test whether you can make a technical product work inside a customer's world and explain it to the people who bought it. The title is slippery. At a software company it usually means an engineer who owns customer integrations. At a hardware or semiconductor company it often means a field or sales applications engineer who helps customers design a component into their product. Federal job data files the title in more than one place. O*NET lists "Application Engineer" among the reported job titles for mechanical engi

Design Instagram's feed: system design in 5 steps

A home feed must return the newest posts from every account a user follows, in time order, within a latency budget, while reads outnumber posts by about a hundred to one. The design question is where the work of merging those posts happens: on every read, on every write, or split between the two, and what each choice costs in operations, memory and tail latency. Interview question: "Design the home feed of a photo app for 100 million daily users." Prerequisites Requests per second and peak load. Capacity is planned for the busiest second: divide a daily count by 86,400, then multiply by a stat

Triage a job description with 40 lines of Python before you apply

Most advice on tailoring a resume starts with "read the job description carefully." That's true and nearly useless, because a posting is a messy blend of hard requirements, wishlist items, and boilerplate. Before you rewrite anything, it helps to know which lines actually matter. Here's a small, honest approach: treat the posting as data. Split it into lines, classify each by how strongly it's worded, and compare against your own resume. It won't replace judgment, but it turns a vague feeling ("I think I'm a fit?") into a short list of concrete gaps. Why wording matters more than position Recr

Your Next Developer Interview Might Be With an AI. Here's How to Actually Pass It

You apply for a dev role. A day later you get an email: "Congrats, you're moving to the next step!" You click the link expecting to book a call with a recruiter or an engineer. Instead there's nobody. Just your webcam, a question on the screen, a countdown timer and a little red recording dot. Welcome to the AI interview. If it caught you off guard, you're not the only one. This is way more common than people think Greenhouse surveyed almost 3,000 job seekers for its 2026 Candidate AI Interview Report. 63% said they had already been interviewed by an AI, up 13 points in just six months.

30 System Design Questions for Frontend & Fullstack Interviews

System design rounds used to be for senior backend engineers. Now frontend and fullstack candidates get them too, and often at middle level. I run mock interviews with engineers, and the same questions come back from company to company. Below are 30 of them in three blocks. Under each one I wrote what the interviewer listens for. How to practice: answer each question out loud before you read the notes. Give yourself 5 minutes. If you can't name a trade-off or a failure case, mark the question and come back to it. Part 1. Frontend system design 1. Design an infinite feed like Instagram or X. Th
