“ (Thinking) . . . which exemplifies the perfections of thinking. . .”

“Disciplined,
self-directed
thinking . . . ”
In “everyday” language:
•

Thinking “outside” the box

mistakes—yet, don’t make too many
of them

Use facts provided to develop support
for your conclusions

Worry about decimal-point precision

Ask for more data, clarifying
information

Summarize your analysis
Provide a clear recommendation or
hypothesis derived from your analysis
Highlight any additional information
you would need to know

regardless of progress made or time
constraints
Waffle or be indecisive—have a point
of view and confidently support it
Ask for feedback

Identify any implications of your
recommendations (e.g., competitor
response, client reaction)

Forget the original question
PRACTICAL TIPS FOR SUCCESS


Bring a pen/pencil and a pad of paper



Feel free to pause, particularly at the beginning



Don’t panic—ask questions to clarify facts, learn more information



Structure your analysis before you begin



Think out loud



Be clear about your assumptions



Silence can be golden



Do what makes you comfortable—approach with your personal style, not what you think is
expected

Most importantly, have fun!

Editor's Notes

  • #25 It is interesting to note that the first four types of interview questions listed have a predictive validity for on the job success of just 10 percent. And 10 percent predictive validity is the same level that is generated from a simple resume review. Math questions increase the predictive validity to 15 percent (since it tests intelligence, commonly a key competency for most positions) and case questions raise the predictive validity to 25 percent (and slightly higher for consulting positions). Behavioral and competency interviewing, on the other hand, yield a predictive validity of 55 percent. Still far from perfect, yet much more reliable for most interviewers. Interestingly, the first four question types are still the favored approach by most untrained interviewers, simply due to lack of experience. Behavioral and competency interviewing is gaining greater acceptance by trained interviewers because past performance is the most reliable indicator of future results, especially when it is tied to the specific competencies for the position. Companies such as Accenture have modified this approach with specific critical behavioral interviewing to target those behaviors which provide the highest correlation with the required competencies for highly predictive positive results.
