I had two interviews and a technical exam.
The interviews were very easy and comfortable. They asked standard interview questions such as tell us about yourself and why do you want to work here. Nothing tricky just make sure you have a lot of questions to ask as they like this.
The technical exam was made up basic SQL queries, basic IIs questions, basic Window questions, questions on Unix commands, and basic troubleshooting.
It can take from 30 minutes to an hour depending on your experience.
It is either hard or easy depending on your experience.
