Toxic bullying nightmare

Recommend
CEO approval
Business Outlook

Pros

A wide array of average benefits. Some flexible schedules.

Cons

3-year 401k vesting. Very low PTO accrual. Bad management. Sentinel program management is horrible. The job postings are very misleading and managers do not understand how to construct an effective team. The culture is very toxic and turnover is high. Unrealistic expectations and they bully people into quitting. Avoid at all costs.

Do not apply for Sentinel

CEO approval
Business Outlook

Pros

Comp package is average. Average benefits.

Cons

The management on SEIT/DevStar under Sentinel is horrible. Most people quit around 12 months. Managers are extremely toxic and openly bully people. Managers hire their friends and play favorites. Daily micromanagement and bullying. Please do not apply for anything Sentinel related. This program and their management is the worst.
