I hope my experience helps, I had went through the interviews and I also participated in interviewing people at LinkedIn
If you are being interviewed by LinkedIn for sales position, the process are generally like this:
1. Recruiter screening - usually being done by phone
2. Meeting: with a senior peer colleague, (probably with recruiter again)
3. Meeting: with hiring manager
4. Panel presentation / interview
5. Meet with a senior leader
Sometimes it will be reduced to 3 steps but the experience will be pretty much the same.
A few other things LinkedIn is looking at when trying to make a hiring decision, besides skills, experience and capability. Culture fit and passionate about LinkedIn is important, you are expected to learn LinkedIn and its ecosystem before the interview, you suppose to have some understanding on: Talent solution, Sales Solution, Marketing Solution what we call "hire, market & sale"). If an external is too proud and not bothering learning more about this, even qualification may be good, the likelihood of being hired is low.
3 key things you need to demonstrate during the interview:
Leadership, leverage, result
During peer and manager interviews, important factors to consider is whether you can FIT into the culture and the team members are comfortable working with you. If you are over aggressive sales or too formal making them feel boring, it is unlikely you will get hired. Sometimes hiring decisions are emotional.
