After  Software Testing @Facebook  and @Google  we shall now look at Microsoft: Testing@Microsoft Software Development Engineers in Test (SDETs) are usually just called Test and sometimes Software Testing. SDETs are responsible for maintaining high testing and qualityassurance standards for all Microsoft products. Software Development Engineers (SDEs) are often referred to as Software Development.
