Research for usefulness, not volume
Understand what the firm does, your office, your service line, a couple relevant industries, why you applied, and your interviewers professionally.
Accounting interview research
How Much Should I Research an Accounting Firm Before the Interview?
Enough to understand the firm and ask good questions. Not enough to recreate the corporate history from memory.
Research My Interviewer FreeResearch these first
Firm size
Services
Office
Industry presence
Role description
Recruiting materials
Interviewer career background
Optional research
Recent relevant firm news or a professional initiative can help when it genuinely connects to the role or your interests.
Usually unnecessary
Every acquisition
Every office
Every executive
Revenue by geography
Twenty years of merger history
The practical test
Can you answer Why Us without quoting the careers page?
Can you ask two or three thoughtful questions?
Can you explain why the office or role fits you?
Warning sign
If every behavioral answer somehow becomes a reference to the firm's 2018 acquisition, the research has stopped helping.
Research should make conversation easier
Know enough to be specific, then stop before your preparation starts sounding like a corporate trivia competition.
