1. There is no career growth opportunities for people with technical background. Most of the science teams at the level of directors/VPs are led by non technical people. In my organization, the average time for non technical people to get promotion was around 1-2 years but for technical people was more than 3.
2. A large number of technical teams have non technical managers. Such managers have a hard time evaluating the quality of the work that their employees has accomplished. Instead, they rely on gut feelings and biases to give promotions
3. The performance review and calibration is so flawed that managers can easily game the system. No one checks the accuracy of performance reviews and managers can easily fabricate the evaluation forms and get employees fired
4. If your manager wants to give your position to his friend or just simply does not like you, there is no one at eBay (including HR) to stop that from happening. There are numerous times that HR assisted managers in creating a paper trail and getting employees fired
5. Although HR claims that they are interested in diversity and inclusion, they do not actually care about such issues. If you have issues related to that, HR puts you in the layoff list.
6. If the team culture is toxic and your manager does not care, there is no one at eBay who helps
