I applied in-person. The process took 2 weeks. I interviewed at Nokia (Kifisiá) in May 2019
Interview
At first they contacted me and arranged a date to take a quick technical test. The test questions were divided into three parts:
1) Programming language (you chose which between a few, I chose C)
2) Linux / Bash Scripting
3) Networking
The test wasn't particularly difficult but it is better to study a bit beforehand.
When I finished the test I sat down with three people from different departments in the company and had a quick talk about my resume and a few basic technical questions. Then they explained what each department did and how they worked.
After that I got a call to schedule another interview, that was more technical than the first. It consisted of some simple questions about C/C++, networking and some more practical exercises. I had to solve two problems by writing a few functions (by hand in c). The last was more complicated than the other with pointers and structs but nothing too difficult.
In both interviews the interviewers were very nice people and the process went pretty well.
The one complaint I got was that they never contacted me to let me know I didn't get the job, which is really not professional, especially from a large company like Nokia.
I applied through college or university. I interviewed at Nokia (Bengaluru) in Aug 2019
Interview
There were two technical interviews of one hour each and one HR interview. It mostly consisted of questions from data structures and java. Some questions about the projects were also asked.
Interview questions [1]
Question 1
It started from basics of java to in depth concepts. Few questions from data structures were asked. Same questions were asked to solve with different approach.
I applied online. I interviewed at Nokia in Mar 2016

First phone call by a recruiter from LinkedIn. The recruiter scheduled an online coding challenge using coderpad. The question was about
Binary Search in a rotated array. Find the minimum number. Classic algorithm question. The interviewer was pleasant and managed time well.
