Robert Bosch Embedded Developer interview questions

Applied on company website. Got contacted via email to chose appropriate slot for interview. 1st Technical Round easy questions. After few days HR just told a slot for 2nd round without asking availability then late night before interview sent mail for Managerial Round with a different time slot. When I sent email about clarification just 10 mins before confirmed that now just Managerial interview (Revised 2nd) will happen on new time slot given. After managerial interview no contact from HR even after several emails from me asking about results. Suddenly after 10 days another HR called about another technical round (3rd) on same day in evening. After this round again no contact from HR even after repeated emails to ask about status. Several days have past. If flexibility is expected from candidate to adjust to your timings for interview atleast keep decency and professionalism to give results. Doesn't pickup call or reply to emails. Wasted my time on interviews and prep. Sorry for long post but really frustrated with unorganised process. Overall 1 month process. All rounds on skype .

I applied through Bosch website and one day hr called me and enquired whether I'm interested and arranged for an technical interview through skype.After technical manager asked some relative questions regarding realtime applications.The interview panel was very friendly.
