Senior Android Developers
The same principle that we wrote about above works here: it is better to pay attention not to the number of years worked by a professional, but to the projects on which he worked. So, senior Android developers, as a rule, were already engaged in large complex projects, led them and managed by a team of less experienced developers.
Of course, to find a mobile developer on Android, it is important to understand the technical features of the position. So, when selecting Android developers, pay attention to their knowledge of Java, experience with the API and knowledge of the principles of backend at least at a basic level.
Pay attention to soft skills as well: it is a mistake to focus only on hard skills, since soft skills, among other things, will help you navigate how the candidate fits in spirit and culture into a particular company, how they build communication with a potential employer and interact with the team. Take a closer look at such soft skills as the ability to work in a team, leadership qualities (especially if you are recruiting senior Android developers who will manage the team in the future), communication skills and the ability to take responsibility for their decisions.
