If you're serious about finding a dream job you need to simultaneously interview with 10-15 companies. Doing this takes A LOT of time - the first interview at Postscript was a take-home video (4 questions, 2 minutes each) and if you pass the recruiter will get back to you. This was amazing as it allowed me to do it when I wanted, under no pressure. After this you will speak with a hiring manager - as much as they interviewed me, I interviewed them (they gave enough time for this and implored it). There were a case study and a few more calls with the founders and other team members throughout the rest of the process.
