Passing the Google job Interview!

Oracle Database Tips by Donald BurlesonJanuary 4, 2015

There are a handful of Oracle shops where everybody wants to work because they are so selective and offer amazing employee benefits.  With the average DBA salary exceeding $70,000 per year the top Oracle superstars can earn as much as $200,000 per year.  Here are some of the most coveted employers of Oracle DBA's:

  • SAS - SAS Campus is world renowned and jobs are highly coveted.

  • Google - Google only interviews less than one of a thousand applicants and hires less then one of out a hundred interviewees.  Last year, Google hired dozens of Oracle professionals, the cream of the crop.

  • Oracle Corporation Development - The systems engineers who develop Oracle are hired from the worlds most selective universities.

  • Burleson Consulting - BC hires less than one out of every thousand applicants.

Far and away, the most notorious job interview questions are from Goggle.  I interviewed with Google and I was asked how to develop an algorithm where you can enter one of three doors with an equal probability by tossing a fair coin.

The Wall Street Journal just published this great article of Google job interview questions.  Check out the last page of the article for detailed question and answers.

Being an Oracle DBA is more than technical skill.  As a lead database architect you must work directly with end-users to design data models to fit systems requirements and this requires specialized thinking ability.

The Monty Hall question:

In some Oracle job interviews, questions are designed to see how well you think about abstract problems.  A favorite is the "Monty Hall" problem.

1 - Contestants are shown three doors.

2 - Behind one door is a new car, while the other two doors have a "booby prize" (a goat).

3 - After the contestant picks a door, Monty Hall reveals a door that he knows to contain a goat

4 - Monty then asks the contestant if they should switch doors of stick to their original choice.

To maximize your chances, please choose the correct option:

a) Always stay with your original choice.

b) always switch to the other door.

c) It makes no difference.

To fully understand the underlying probabilities, see this Youtube description of the Monty Hall Problem.
