Pros
While the salary is rather average, the other benefits (medical, RSU, ESPP, 401k) are actually fairly generous. There are some really great, highly-skilled people you get to work with. Maybe it's Stockholm Syndrome talking, but it's the good ones that make it possible to get through the day. As you'd expect for a West-coast company, the company is very focused on diversity and inclusion.
Cons
It's truly unfortunate at what cost the company's recent success has come. 5 years ago I would have happily recommended the organization to peers and prior colleagues. Now I feel a pang of guilt when we hire someone with great experience with a positive outlook because they will be broken within a year. The company takes their top performers, chews them up, spits them out, gives them no credit, and holds the door with a smile as they walk out to a better opportunity where they are respected. Prepare for some of the worst work-life balance you have experienced. It's a slap in the face because senior leadership stands in front of the employees, reviewing harsh survey feedback and say they encourage everyone to take time off, to maintain a healthy balance between work and home, and yet they set completely unrealistic expectations and deadlines such that if you dare to take any time off or fail to work 10-12 hours a day, nights and weekends you are going to be penalized. Taking even a single day off is stress-inducing because when you return to office your work life will be miserable. And good luck getting approval for additional headcount in your group! 5 years and counting with multiple new products, new processes, new systems, new responsibilities and nothing except longer and longer days. And with the extreme daily expectations comes overworked managers who don't even have time to spend with their direct reports, to coach them, to develop them, to recognize them for their successes, or to promote their careers. The promotion process is a ridiculous multi-month process full of painfully detailed essays, surveys from peers, managers fighting like gladiators in front of senior leadership to get unanimous approval of 12-20 other leaders, many who probably don't even know the person up for promotion, all of which you get to repeat if you happen to fail. Every quarter. For each of your employees. You can see the unhappiness in people's faces. Hear how tired they are from being overworked. And clearly see when their backs break and they are in the process of finding a less toxic environment to call home - away from Seagen - taking their talent with them. All completely avoidable if the organization cared.
