Company Name :Datazoic Private Limited.
The Interview Process took 1 day.
The first round was aptitude.
Depends upon the HR mood.For us due to the less time they give 15 c technical question in time duration 15 minutes or
They gave 10 problems and asked us to solve it in 30 minutes.
There are about 600 participants.
100 to 150 moved to next round.
Second round was coding.
Totally 6 problems,the time limit is 90 minutes.
For system programming use any language you wish , But they dont allow you to use IDE , instead use notepad and run in command prompt.
Then final round in company.

Odessa Technologies Interview Experience
I applied for Software Engineer post in Odessa technologies through my college on campus drive.
The preliminary round was based upon solving 3 programs given through skill rack platform. 10 students were selected from my department to attend the drive. Approximately 50 from our college.
On the day of the drive we were given two choices either to apply for software engineer or software quality tester. 8 of us chose to apply for software engineer and 2 chose software quality tester.
The first round for software engineer job was held in Hacker Earth platform. The test contained 18 MCQs based on aptitude,verbal,logical and flowchart interpretation.Followed by it we had 3 programs one of easy category worth 50 points, one of medium category worth 100 points and one of hard category worth 150 marks. We were provided totally 1 hour 30 minutes to finish the first round.
I was able to solve the easy and medium programs but i had time complexity issue with the Hard categorized program.
The first problem was based on Arrays, The second was based on strings and the third was based on constraint satisfying problem within the given time complexity.
None of us made through the first round, but it was a good experience to solve the problems.
My friends who attended software quality testing said that they had two rounds and the first round was fully based on aptitude, logical, verbal MCQs and it was a bit easy, the second round was based on programming, but none of them got through the first round to attend the next.

Cisco Interview
Status: Full Time job + 6 month internship offered.
It was a 4 round interview. The first round was a written round with 50 questions(20 aptitude + 30 technical) for 1 hour. The second round was a technical round(1 hour). The third was a technical + management round(20 mins).The fourth round was a short HR round(10 mins).
In the first round, 20 aptitude comprised of simple-medium-complex aptitude questions.Some were answerable within 10 seconds, some took 30-40 seconds and the harder ones took slightly over a minute to solve. The questions were based on all the classic aptitude topics.Some questions were stated in a confusing way, but other than that, no hiccups were present. The technical side had 30 questions. roughly about 10 from C, C++, OS were asked, another 5-6 were from electronics side.Around 5 from networking topics and the rest were based on data structures, complexity estimation,and topics around that. I was able to answer most of the aptitude questions(17-18) were correct out of 20 and more than 22 questions were right out of 30 in the technical side. I think the cutoff for the second round was around the 40 mark, which i had gotten and i made it to the second round.
In the second round, the interview started off with simpler,shorter questions, like for example the interviewer pointed to one of the technical questions in the previous round(the interviewer has your answer sheet from the previous round) and asked me to explain the approach i had taken to solve the problem. The question he asked me to explain was a recursive function, and i had to estimate the worst case time complexity of the function. the function was something like this.
function(params)
{
...//terminating condition
else..
return function(params-1) + function(params-1)
}
The answer to this was O(2^n). The interviewer modified the question to this:
return (function(params-1) + function(params-1)) * function(params-1)
The complexity of this was O(3^n). He asked me to derive it on paper which i did. The next question was regarding how to set the nth bit in a 32bit-integer. The answer was pretty straight forward. variable | 1<<(n-1). The next question was about a linked list. The interviewer asked me print a singly linked list in a reverse manner. After that we moved on to trees. The first question was to find the min element in the tree. The second question was to implement level order traversal in trees. After i did that, he asked me to traverse the tree and print it in reverse level order fashion, but the associativity of the child node should be from L-R. for eg..
4 Then the answer would be:
/ \ 1357264
2 6
/ \ / \
1 3 5 7
After taking a few hints from the interviewer i was able to code it up without errors.
The next question was to print the tree in a zig-zag manner. ie:
for the tree above the zig-zag traversal would yield: 4267531.
After thinking for some time, hints from the interviewer, i was able to code this up as well.
Basically by this time 1 hour was up. The key points the interviewer looked for, was my approach to the problem, error-less coding, All corner cases must be taken care of while implementing the program.The most important thing is you should be sure of your solution. The interviewer asks you if the solution is right or wrong, here he is checking your confidence, try to dry run the program once or twice after coding it up, this would help with the confidence. Also , try to speak as much to the interviewer about your thought process, this not only gives a better opinion to the interviewer, but if you tell him where your stuck, he/she might give you clues to proceed further.
After answering all the questions with hints from the interviewer , i qualified for the next round.
In the third round, The technical-management round., the key focus was your thought process, they were not too keen about the technicality of the solutions. The interviewer asked me what were my favorite topics, and i replied data-structures and algorithms. Then he asked me to code up a part of a social network were people were nodes and different types of connections existed between them. my job was to write functions to connect any two nodes of the graph, and also another function to check if 2 nodes are directly or indirectly(transitively) connected.
I asked him, whether all these edges/connections were directed or undirected, so he asked me to assume they were undirected for simplicity. Then i was asked to come up with a data structure to handle these operations. It was obvious that it was a graph structure and the nodes had user details and a edge-list inside it.
the socialGraph class had a insertion,deletion functions and connect(node*,node*) ,
isconnected(node*,node*) functions as friend functions to connect 2 nodes and check if 2 nodes are connected. connect function was straight forward ,as i had to append node reference to the edge-list of the node.
Then to check if 2 nodes are connected, i did a DFS from the source node to the destination node. The interviewer asked me to make the code such that it could scale. So i suggested that we could do a A* search instead of a DFS to make the search space smaller. The interviewer seemed satisfied with my solutions and then we moved on to the other questions. He asked me about my projects, the roles i have played in various clubs in the college, my future plans, why Cisco? and other simple questions like that.
I did well enough to get qualified for the final round which was a casual HR round where they asked simple questions like the meaning of my name ð??? and then i was given a evaluation form to fill, and they asked me some questions on that which i could answer.
The interview overall was reasonable, but certainly made me think out of my shoes, and strong knowledge in Data structures and algorithms helped me pass this interview.
