Pros

- CLIA team are all hard workers, they TRULY are the heart of the company - new laboratory is significantly larger and spacious - it's a startup, so really allows frequent opportunity to interface with both members of other departments and also up the management chain

Cons

- compensation is low, especially for non-management roles. - peer review cycle is extremely biased, results in resentment and creates toxic work environment - Managers frequently get promoted every review cycle and individual contributors are ignored

Business Outlook

Pros

People and culture is great overall. Business is doing well. People are smart and hardworking. Free lunches, snacks, and frequent parties with food and drinks.

Cons

Most lower level jobs are poorly paid. Hiring only hardworking superstars but only a small fraction gets promotions and merit increases, no bonus no annual raises otherwise, so the base salary can becomes not competitive pretty quickly. Career growth between different departments are mismatched, some departments advance people to high levels much faster than others. CLIA and R&D have hardworking people stuck at some levels. Many people are waiting for the market to warm up to leave for other opportunities.
