   # Introduction
<div class="ans">
<p>Tech interviews can come in multiple forms. One is a problem-solving, algorithmic, brain-teaser type of interview, which aims to discover a candidate's intellectual horse-power. The second category of tech interview questions consists of open-ended system design interviews. These questions explore a candidate's experience and maturity with building large-scale systems from scratch. The third type of tech interview questions is language or technology specific questions. If a candidate claims forte in Java or Python on their resume, then questions digging into the guts of the language or the technology platform are fair game. Usually, companies hiring for contract, short-term positions or for very specific technologist roles will interview for the last category.</p>
<p>Unlike the algorithmic coding problems or the system design questions, technology specific questions generally don't have any <i>gotchas</i>. A candidate is largely required to draw upon one's memory to answer these questions. The best practice for these questions is rote learning the realm of all possible interview questions for a language or technology.</p>
<p>This course is designed to prepare you to nail any level of Java language interview. If you are a Java veteran, you may use the course as a refresher or if you are a newbie to the profession you may use the course as primary preparatory material. In either case, the course would impart new learnings and challenge your existing knowledge on the subject matter.</p>
<p>Goodluck and Godspeed!</p>
