The whole recruiting thing had 3 parts, first an assessment, then a phone call, and finally on-site interviews. Honestly, it was an okay experience. We talked about OOP concepts and data structures, mostly in Java. I thought the interviews were pretty easy.

Technical Behavioral
The interview process had good managers and mindsets. The technical interviews were great, focusing on problem-solving and SOLID principles. However, the HR person was unfriendly and late for the on-site interview. I didn't get feedback because I said I could only do 2 on-site days, not their requested 4, and my salary expectation of 40K was too high for them.
