Pros

Talented and supportive colleagues in many teams Opportunities to work on interesting projects Some flexibility in work arrangements

Cons

The company regularly lays off qualified employees, sometimes in large groups, with little warning, often favoring cost savings over performance or contribution. Management is not transparent—line managers often cannot explain strategic decisions, and upper management rarely shares the financial situation or reasoning behind layoffs. Terminations can happen via a single call with minimal support or explanation, which is demoralizing and stressful for employees. Career growth and job security are unpredictable due to frequent restructuring.

Pros

Flexiblity re hybrid work culture diverse team of professionals

Cons

Management issues - I was working for an FSP and my manager at Syneos failed to give me guidance and feedback in order to satisfy the work culture at the FSP. My manager suddenly changed and new management abruptly let me know that the FSP were not happy with how certain work issues were being fulfilled by me etc. Poor management and poor follow-through from management.
