I worked at Conversant full-time (More than a year)
Very good people to work with and have a fun atmosphere. Salaries are OK and the bonus makes it a good place to be.
Putney is a bit out of the way from the London 'vibe', and the office can be a bit crowded at times.
Advice to Management
Keep doing the same as you are and keep hiring good people
I applied online. The process took 4 weeks. I interviewed at Conversant (London, England) in September 2017.
Had 2 telephone interviews and 1 face to face interview which took place over about 4 weeks, with a lot of chasing from me to try and get them organised. Never heard anything back after the face to face interview (literally nothing, not even an email) but they said there were either 2 or 3 more stages after that.
