Practice 611 real interview questions with 30- and 60-second spoken answers, then rehearse with mock interviews that ask follow-up questions just like a real interviewer. Start with an 8-question career test that suggests a role that fits you (10 engineer roles, such as Recipe Wizard, Data Detective, and Tool Guardian Knight, plus 2 production roles: production operator and equipment maintenance). Then My Curriculum builds a week-by-week study plan for your deadline and daily study time. โ Key features 1. 611 interview questions in 22 areas Process, device, circuit, equipment, metrology, packaging, quality, HBM, AI chips, materials, production roles, and behavioral. The first 2 questions in every area are free, with answers. Each has the interviewer's intent, key terms, 30- and 60-second model answers, follow-ups, and common mistakes. Graph questions ask you to read control charts, wafer maps, device curves, and FDC traces. Rate yourself, and questions to review are collected for you. 2. Mock interviews Pick one of 7 role tracks and answer a 5- or 10-question set. Follow-up questions come just like a real interview, and you get a report at the end. 3. 199 in-depth lessons + 21 free basics lessons 162 major track lessons (device, circuit, process, packaging, quality), 19 role guides, and 18 resume, interview, and aptitude test tips. The 21 semiconductor basics lessons and one advanced lesson in each major track are free. 4. 199 real-world troubleshooting cases Find root causes the way fab engineers do: yield, SPC, trend charts, commonality analysis, reliability, incident response, material qualification, equipment alarms, metrology calls, packaging defects, process defects, GR&R, and PI defect tracing. Write up solved cases as 8D reports, then turn them into STAR stories and 1-minute interview answers. 5. 27 games, a 3D fab shift, and labs - 3D cleanroom fab shift: walk 12 bays, see how tools work, and take on job missions and shift plans - Process simulator with 24 stages - 5 process condition labs: change lithography, etch, deposition, implant, and CMP conditions and see the results - 5 circuit labs: inverter, SRAM 6T cell, DRAM sense amp, timing path, and analog circuits - Metrology reading room: TCD/BCD sites, FEM and Bossung curves, TEM and SEM review images - Defect atlas: 12 processes ร 57 defects - Wafer map quiz, device curves, yield calculation, a chart reading atlas, and more 6. 4 process flow charts DRAM, 3D NAND, logic (GAA), and HBM step by step with cross-section animations and interview points. 7. 571-term glossary + speed quiz Search terms, review adaptive flashcards, and take a 60-second speed quiz. 8. Level up and daily quests Earn XP and level up to Lv.30. Each role has 5 ranks, its own character, and promotion quests, plus daily quests. โ About passes - Some content, including the semiconductor basics lessons, is free to try. - There are two passes: the Lifetime Pass and the 90-day Season Pass. - Both are one-time purchases. They do not renew or charge you again automatically. - If you have a Season Pass, you can upgrade to Lifetime by paying only the difference. - You can buy a pass and use it right away without signing in. Reinstalled the app? Tap "Restore purchases" with the same Apple ID. - Payments and refunds follow App Store policies. โ Privacy - Your study records and bookmarks are stored on your device. When you sign in, they are backed up so you can continue on another device (up to 2 devices per account). - Sign in with your Apple or Google account. You'll see a prompt on first launch, and you can skip it with "Maybe later." - Signing in is optional. When you sign in, your pass and study records are linked to your account, so you can use them on your other devices. - You can delete your account yourself from "Delete account" in the app menu. โ Note Study materials and sample answers are for reference and don't guarantee a job offer.
