Orange Business Java Developer interview questions

First round was Computer based test which included MCQ and 3 coding questions (quite easy). This happened on day 1. Then HR didn't confirm the results. After 2 weeks, I got a mail stating, first round had been cleared. 2nd round included one technical f2f interview and then managerial round. After clearing these two, HR discussion happened. HR asked me to send all the required documents (salary slips, appraisal letter etc). I send these on the same day but after that I never heard back from him. I mailed him, tried to connect over call but he never picked nor did he cared to revert back on mail. Never expected this kind of behavior from such a reputed company. If they don't want to hire then don't but atleast don't make the candidate wait, atleast respond back!!
