REHEARSE THE WHOLE DAY Prepare for one interview or a full five-, six- or seven-round superday. Meet distinct fictional interviewers, from junior technical rounds to a senior fit conversation. Each round has its own introduction, focus and pace. Practice spoken answers on iPhone and iPad, with transcription where supported, or use tapped answers. Web interview practice uses typed answers and self-assessment. UNDERSTAND THE WHY Go beyond the correct answer with worked explanations and key takeaways.
