Poor advancement opportunities. I went to LinkedIn specifically to advance my career, making it very clear when I got hired that my biggest fear was doing the same thing I had previously done. LinkedIn poached me, so I thought the hiring manager would have realized they couldn't expect me to do the same thing for a year.
Unfortunately, this is exactly what happened, so I left a year later. Ad Operations is notorious for this in the industry, but it is especially true at LinkedIn. It seems exciting because LinkedIn is an awesome company with very smart people, but it has also grown far too quickly to give real career opportunities to the majority of employees. Many in my department either leave the department or company in order to find their next step. Senior titles aren't really different. They need to seriously reevaluate their advancement structure.
The middle managers also aren't great. They don't have enough experience to really help support the ICs and are also very lacking in their ability to have career conversations or provide training. Leadership also had a lack of professionalism that I don't think is right to talk about here, but made me lose a lot of respect for the company.
Big picture - The company is a great, exciting company to work for. I would recommend working here, but not as a Campaign Manager to anyone that has experience in it. Great for a first job, not so great for a second or third.
