"Halo of Knowledge" Trap: Excel in your current role doesn't guarantee interview success. Practice interview questions, code on paper or online, and do mock interviews to adapt to new requirements.
Being tired: Schedule interviews when well-rested, as tiredness impairs cognitive function and problem-solving abilities.
Not picking up on hints and going down rabbit holes: If stuck, request interviewer clarification and pay attention to their cues and body language.
Not preparing for behavioral questions: Be ready to discuss past experiences that demonstrate your soft skills and cultural fit, as behavioral questions often revolve around such examples.
