I applied online. The process took 1 week. I interviewed at CCS Global Tech (Philadelphia, PA) in May 2015
Interview
-- First Round Phone Interview: self-introduction. Prior experience description. Concepts Check.
-- Second Round Face to Face Interview: Scenario analysis. Writing Code. Discussed a lot about my personal experience in data engineering and data science area, such as tools, languages, system topologies, etc...
Mostly asked questions on SQL, covering concepts like normalisation, DBMS, asked me to write 2-3 SQL queries, and finally some Python and machine learning concepts. It was overall a medium-level question, so mostly prepare on basic SQL concepts and Python concepts.
