I applied with via Linkedin. NI returned in ten days.
The recruiter shared meeting code for hangout in CEST timeline.
Unfortunately, I joined the first interview with 10 minutes delay.
It was my fault, related to a misunderstanding of the time zone.
Although getting off to a bad start, The recruiter's energy was positive and relaxing. The recruiter was very kind, understanding and offered to postpone the interview, but I prefer to move forward.
Actually, questions were not hard and extraordinary. Just related to NI and job description of the position. At the end of the interview, the recruiter asked my questions. Then, they answered my questions concurrently.
Roughly one month after the interview, the recruiter firstly requested a call about feedback their recruiting process. The recruiter had informed me in a call; they move forward with another candidate for this position. Their decision not shaped with my audio meeting performance but other candidates experience and skills.
Not only NI's products and service but also their HR's interview process was shiny. NI's HR process is very parallel with their web page. NI's HR process is honest and open and cares about the people.
If you look NI's Career Page, (including FAQ) this guides you perfectly.
