Here's a summary of my interview process:

• HR screening interview
• Hiring manager interview – this was informal, and we had good chemistry.
• Pull request pairing interview – booking this took time due to holidays. It went quite badly because I didn't know JS/TS, and our expectations were unclear. I communicated my feedback clearly and without blame, which I'm glad I did.
• System design interview
• Test-driven design interview – this was added at the last minute, much to my displeasure. However, it wasn't difficult, and it was nice to meet my division manager.

Due to some delays in the process and the last-minute addition of the test interview, I was unhappy with the process and communicated this to HR and the hiring manager. We managed to work out an acceptable arrangement in the end, and I completed the extra interview. While I wasn't entirely happy about some miscommunications on the recruiting side, my hiring manager was very helpful and fought for me. This increased my motivation to continue, and I happily accepted the offer I received. I've been here about a year and am happy I insisted.

Nothing on the technical level was too difficult. The challenge was more psychological. You need a lot of patience, but you will get patience in return as well.

Hiring manager: What achievements were you most proud of? What things are you less proud of? What tech stack do you like to work with?

System design: Walk us through a system you were involved in designing. Show us one of the changes you made.
