Impossible hours. You will be expected to come in from 10am to 10pm while working in Berlin. This does not get better for remote employees; time zones are not respected. Calls and emails at all hours, and you ARE expected to respond. Little to no time off.
Day-consuming meetings that will go no where.
Inconsistent focus on target audience, ideas, and... pretty much everything. Scatter-shot techniques without proper time for anyone to prepare.
Constant responsibility whiplash. Because so many people quit, jobs are handed off without much training or, once more, preparation. CEO expects you to just get it anyway.
Disrespectful tone in office about authors and publishing. Site users are often brushed off when asking questions. As several blogs have reported, online stalking and IP blocking were used against bad press.
Management wholly inexperienced and unprofessional. Their CEO will sour the job if the hours do not do it first. Stubborn, quick to blame, and quick to anger, there will be no pleasing him. Co-founder is usually unavailable and hard to contact. You're on your own otherwise.
Temps and student workers are offered publishing experience, but are pushed to take the same hours for very little pay, and given some especially unpleasant responsibilities (cleaning, shopping for CEO, spamming Facebook, etc). Inkitt went through temps so fast, and there was a real reason for that. Please reconsider this before taking the job with any study abroad programs.
