The first phone call was from the manager. Basic Technical question from the resume skillset. The second phone call was with the team. Group of 3 interviewers asked questions turn by turn on a variety of technology.

In short, SIEMENS is looking for cheap labour than a skilled worker.The interview consists of four rounds. 1.) Programming Test 2.) Technical 3.) Managerial 4.) HR The process will take a full day as their interview process is not streamlined. They will call you in the morning and take one programming test and then there will be hours(min 3-4) of waiting before next round starts. The worst part will be HR round, even though your technical/managerial interviewer is happy with you and willing to pay you a good sum(30-40%), the HR will shot your negotiations down to 5-10% max. They'll be hardly interested in the skill that you'll bring to the table and just interested in the number and will try to sell you the brand value(:D). Attend the interview only if you don't have other options.
