      Entrevista

      First I had a telephone interview with HR, then an online cognitive test (non technical). Second interview was a call with a senior developer with technical questions including java, sql. In the end of the interview a part of code is shown and a description of the output has been asked. Final interview including both HR and team leader/manager. Overall, it was a positive experience and a good feedback about the practices used has been given and why those practices were preferred over others.

      Entrevista

      There were 2 1 hour long technical interviews. The first part of the first interview was with a senior developer in which we discussed my previous job, my experience with java and the company's product which I would be working on. The second part consisted of technical questions about Java along with solving a bug in a code given in a snippet. The second was with the head HR and a project manager. The hr asked questions about why I want to join the company, why I left my previous job along with questions describing my intent and my motivation about taking on the job. The manager asked more broad technical questions, as how I would implement a database given a performance problem with some queries. It was overall a good experience although It felt like the role was highly competitive, as I answered most of the questions and got a negative reply.
