Technical Interviewer Guide: The golden tip

I’ll jump right into it: As an interviewer, ask all your questions strictly in the past tense. That’s simply all what’s there to it.

TechTalk: Lambda architecture and real-time processing (Arabic)

Although Hadoop might be the first thing to come in your mind when you think of processing large data sets, it is not always the best solution for your Big Data problems.
Hadoop might be the right choice for batch-processing big data, but when it comes to real-time data processing there are other architectures and tools to consider.

The talk is recorded in arabic as a JOSA TechTalk event on Jan 31st, 2015.
