I worked at Sapient full-time (More than a year)
Lots of travel, a high quality of people and talent, high tech projects, ability to work on pre sales projects and pitch to clients. Trusting environment.
No formal tech training. Incredibly high work hours. Can be a stressful environment at times. Workshops are brutal on the hours.
Advice to Management
Not enough r&d
I applied online. I interviewed at Sapient (London, England).
The interview process was quite standard. There was an initial phone interview and then a face to face interview. One interview with HR (competency) and another with senior managers which was more focussed. After this, I hear back within 1-2 weeks with an offer. I was pretty happy about that.
