Well first when you enter they will give you an 1) aptitude test questions these questions can be logical or aptitude but they are structured not like some companies who give anything so just prepare like you would do for aptitude test and do word problems. 2)Write programs in ur language the basic fibonacci, patterns, sum of prime nos., so basically prepare for the most asked programs which are asked in companies 3) write sql queries for a given table so practice sql queries 4) this one has html related questions like what is cell padding, cell spacing, write an html program to create a table, basically do the rows and columns ka but dont just trust what I have written it might change also I am just giving you an idea how it will be and what you can expect. The interview with the senior will be after you have completed the aptitude test they will basically ask on oops concept so be well prepared for that and prepare examples also not the theory ones but the program example for how you can use it , be prepared for exception handling, multithreading as these are also important and do work on ur technical skills like programs for java which you should know so prepare well.
