There was few tasks about overriding vs overloading functions, calculating pixels in image due to screen size, asking about OOP principals and also about Android manifest and its field. Whole interview was about 1,5 hour.

Just imagine that they call you on your holiday to schedule an interview. They force you because it is mandatory to sign the contract until that week, so you accept the interview. They did not tell you if it is a junior, mid or intern position. They tell you you do have the experience and it s all good, you go to all the interviews just to tell you at the end that "the client does not want a junior". Then why have you interviewed me?? The HR is a mess, they are not transparent nor are able to give you the information correctly. The manager insisted to have a working student contract even though I had experience of 2 years. Please, do not waste your time. Never in my life I will apply to this company.
