Access Breadth and Depth-find gaps

Do not memorize definitions and read out! Provide examples, not just definitions!

Cite bult-in examples from major frameworks.

Show you understand/have used it.

Don ' t go overboard! (Brevity is beautify)

...

Transactions/acid
Tables vs views

Algorithms & Problem Solving

Measuring Aptitude:

Applying what OU know

Solving "new" problems

"Hands on" vs theory:whiteboarding, writing codes

Thought Process & Reasoning

Communication

Tips:

' Right ' matters less than thought process.

Talk your through the problem.

Break it down. State/clarify Assumptions

Draw/write it out:visualize your logic.

But "knowing the answer" isn't the point, and you're need to being able to explain it!

Get started; How quickly can solve matters.

Write out pseudo code/comments.

State assumptions, think about corner cases.

Example:s

9 balls, same size, 8 is the same weight. Find heavy ball using a balance in the least number of weighings.

Does any of the questions for me? Tips:

Know What factor You "re looking for in a job/company.
