Pros

Great communication and relationships with partnerships. If your contract ends, the recruiters do everything they can to help you get on another contract within Syneos.

Cons

Contract so not permanent employment. However, the companies they work with are reputable and give you good experience.

Pros

Remote work, had a job

Cons

Worked with some of the most toxic people I have ever worked with in my life. Some people were straight up rude and unprofessional. The industry is old school and change isn’t widely accepted. Favoritism for the wrong people and nepotism is real
