The interview is not long, using online conference app such as gmeet, there's only 1 interviewer, the question is kind of fundamental theory like what is OOP. The interview will be easy if you prepare beforehand (reviewing programming fundamental theory)

I applied for the coding bootcamp to be a Jr Application Developer. I found the vacancy on Instagram and applied on their site. After applying, I got a multiple-choice technical test and a psychotest. After that, I was invited to do interview with the training mentor on Zoom. The interview took around 1 hour. The interviewer asked me about basic programming & SQL concepts. I had to answer it on a Notepad by demonstrating what I know. There were no unnecesary questions, all of them were related to the position I was applying. The interviewer also gave me a chance to ask questions about the job.
