Tech Interview Preparation: From Application to Offer
A preparation guide for software engineering interviews, covering the three formats most candidates face — technical screening, system design and behavioral rounds — alongside how large tech employers and startups structure their interview loops, a bank of frequently asked questions, a six-week study plan, virtual interview setup advice, and the behaviours interviewers treat as red flags.
Technical, system design and behavioral rounds
Preparation is split into three tracks. Technical screening covers data structures, algorithms and problem-solving habits such as clarifying requirements first, starting from a brute-force solution and analysing time and space complexity. System design covers load balancing, caching, database design and scaling trade-offs. Behavioral rounds use the STAR format across leadership, problem-solving and collaboration themes.
Company-specific interview processes
Separate guides outline how Google, Meta, Amazon, Microsoft and startups run their loops: the number of rounds, the areas each one weights, an indicative timeline and insider tips. The page notes that Amazon interviews revolve around its Leadership Principles, and that at some large employers a team-matching stage can add months after the technical rounds are passed.
Question bank and a six-week study plan
Commonly asked questions are listed for each format — coding problems, system design prompts and behavioral questions — tagged with difficulty and how frequently they appear. A four-phase, six-week plan runs from foundations and STAR story-building through medium and hard practice to company-specific preparation, with a 45-minute timer for simulating real interview conditions.
Virtual interviews and common red flags
Remote interview advice covers testing camera, microphone and screen sharing well in advance, arranging a clean and well-lit background, looking at the camera rather than the screen, keeping a backup connection ready, and practising in a coding environment you already know. A closing list names behaviours interviewers read as red flags, including speaking negatively about past employers, asking no questions, and not following up.
