Technical Fundamentals & Core Skills Topics
Core technical concepts including algorithms, data structures, statistics, cryptography, and hardware-software integration. Covers foundational knowledge required for technical roles and advanced technical depth.
Estimation & Analytical Thinking
Estimation techniques (e.g., Fermi problems, back-of-the-envelope calculations) and analytical problem-solving approaches used in technical interviews and software engineering. Covers problem decomposition, quantitative reasoning, data interpretation, and constructing defensible assumptions to reach plausible conclusions.
Hardware and Embedded Collaboration
This topic covers cross functional collaboration between hardware, embedded firmware, and software teams to design, integrate, validate, and deliver physical products. Candidates should be prepared to describe translating system level goals into actionable hardware requirements, defining and documenting interfaces and handoffs between disciplines, and aligning development, validation, and manufacturing schedules. Interviewers will probe technical integration skills such as specifying electrical and communication interfaces, timing and memory constraints, device driver and firmware design to match hardware capabilities, hardware bring up and debugging, and the creation of integration and validation test plans. Candidates should also demonstrate cross functional practices including negotiating trade offs among latency, power, cost, and schedule, managing prototype and manufacturing feedback loops, applying risk mitigation strategies such as incremental integration and simulation, maintaining configuration and change control across domains, and communicating effectively to resolve interdisciplinary problems and ensure product quality.
Problem Solving and Structured Thinking
Focuses on general problem solving strategies and structured thinking applicable to engineering, coding, and complex decision making. Core skills include clarifying the problem, breaking problems into subproblems, identifying patterns, selecting appropriate approaches and data structures, developing and testing incremental solutions, analyzing trade offs, reasoning about time and space complexity, handling edge cases, and communicating thought process clearly. Includes algorithmic patterns and design of systematic approaches to unfamiliar problems as well as frameworks for organizing thought under ambiguity.
Technical Problem Solving and Learning Agility
Evaluates a candidates ability to diagnose and resolve technical challenges while rapidly learning new technologies and concepts. Topics include systematic troubleshooting approaches, root cause analysis, debugging strategies, how the candidate breaks down ambiguous problems, and examples of self directed learning such as studying new frameworks, libraries, or application programming interfaces through documentation, courses, blogs, or side projects. Also covers intellectual curiosity, baseline technical comfort, the ability to learn from peers and feedback, and collaborating with engineers to understand architectures and tradeoffs. Interviewers may probe how the candidate acquires new skills under time pressure, transfers knowledge across domains, and applies new tools to deliver outcomes.
Technical Depth and Current Knowledge
Assessment of a candidate's deep technical expertise and up to date hands on knowledge across core engineering domains. Interviewers will probe system design, performance optimization, distributed systems patterns, databases both relational and non relational, caching strategies, messaging and queuing systems, application programming interfaces, cloud infrastructure, observability and monitoring, and relevant programming languages and runtimes. Candidates should be prepared to discuss concrete technical trade offs, debugging and performance tuning approaches, how they research unfamiliar topics to maintain accuracy, and examples of technical decisions they have owned. This topic covers maintaining current technical fluency even in leadership roles and being able to have rigorous technical discussions about architecture and implementation.
