I went through 4 rounds of interviews over the course of a month. I was excited about the position because I think MSD’s technology is fascinating, so I was constantly refreshing my email waiting for a “next steps” email. I was pretty appalled to say the least when I received my rejection through a Linkedln DM. I found this to be extremely unprofessional. If this is considered acceptable at the company, I likely dodged a bullet. I ended up sending an email to the hiring person and got a response a few days later. Appreciated the response, but the initial let down through a DM was disappointing

I applied online. Got a call from HR and had a phone screening for about 20 minutes. General questions: my experience, why this company, etc. Later I received an email with invitation for an interview. The interview was with 5 people, 30 min with each person. Everybody was very friendly and the process was smooth. I got a chance to talk about myself and ask about company. It took a while to get an offer (it had to go through approval process according to HR), but I got it.
