How To Face An Interview

Throughout the engineering spam we all are always keen to know what exactly is asked in the interviews. How many rounds take place? What is the quality and difficulty of the questions?

Well here is the answer to all of those, some personal experiences shared by the students of Pune Institute of Computer Technology. Everything explained in detail about 3 MNC Microsoft, Morgan Stanley and AirTight Networks.

How To Face Interview

 

Microsoft 

Job Profile: Software Developer
Placement Process:

Test--> Technical Interview--> Technical Interview--> Technical Interview
Round 1 - TEST

Experience:
It was an online test. The company who hosted the test messed up with the interface, and a lot of people had trouble with a coding question that could not be solved because of the faulty interface. There was no retest.

Round 2 - TECHNICAL INTERVIEW

Experience:
QUE 1: Given a compact data structure to store strings sequentially, one byte stores length l of the string, next l bytes contain the string characters. Write a code to insert the given string at the ith place, making sure the DS is still compact. Write tests to verify the correctness.

QUE 2: How will you construct parse tree for ((a+b)*c)/d? What all data structures can you use?

Round 3 - TECHNICAL INTERVIEW

Experience:
QUE 1: Given a function f that returns true or false based on whether the input string satisfies some hidden criterion C, write a function that verifies that all sub strings satisfy C.

QUE 2: You hand over 'n' identical linked lists to n salespersons. After the day's work, these salesperson return the lists. Merge these lists such that all insertions, deletions, updates are taken care of, so that you can repeat this process for the next day.

Round 4 - TECHNICAL INTERVIEW

Experience:
Told about myself, my interests, my internship projects and my work so far.
A few coding questions were asked too.
In the end, they asked if i have any questions.

Tips:
Start preparing early.
Develop priorities both sector wise and company wise.
Take sufficient water and food with you. Interviews can start at 8 am on the first day!
Have enough copies of resume and transcripts with you.
If you have been shortlisted for many companies, it is preferable to have a portfolio manager who manages your phone during the day and enables you to focus on the interviews.

10 Unexpected Interview Questions and Answers

Morgan Stanley

 

Job Profile: Software Engineer

One Line Advice: No coding knowledge expected! But get your math well!

Placement Process:

Resume Shortlist--> Test--> HR Interview--> Technical Interview--> Group Activity

Round 1 - RESUME SHORTLIST
Experience:
Started out with learning to identify and portray the focal points in a resume companies are looking for. Then went on to list my achievements (big and small) over the years, and the qualities they reflect about me (the hardest part!!). I then selected the 4 I wanted to put forward, and wrote my resume accordingly.

Round 2 - TEST
Experience:
Written Technical test; 30 out of ~ 200 short-listed; 2 Rounds (1 Tech + 1 (Tech + HR); 15 out of 30 short-listed & 2 rounds (1 Tech + 1 Group Activity); 5/6 out of 15 selected. Test was pure coding syntax. Do not come just prepared with just algorithms! Work in one language and master the syntax. The first tech round was some basic programming problems - Eliminating the originating node in a very large circular linked list in the least computational time. Sorting algorithms - Some basic Inheritance.

Round 3 - HR INTERVIEW

Experience:
The second round was an HR round supposedly. We discussed my work in the startup I was in, and then went on to the system design for the same. Later, He tried to put me off-track with a simple guesstimate (no of petrol pumps in Bombay), and ended with a simpler puzzle (Rectangular plate with an arbitrary rectangular hole to be divided into 2 equal halves).

Round 4 - TECHNICAL INTERVIEW

Experience:
The third round was more technical with some more basic algorithm problems & - Traversing a 2 - dimensional array in a spiral fashion - Syntax of commands in C (the language I had chosen for the test, others were Java and C++) - OOPS concepts.

Round 5 - GROUP ACTIVITY

Experiences:
The fourth round was a group activity where a team had to build a model building with straws, come up with a marketing campaign for the same, and make a presentation of the same at the end of the day.

How to face an interview:
Prepare your programming language syntax well. That is where most people lose out in the written tests.- The people here are not looking for very high tech stuff, just some basic programming skills and very basic algorithms, so go through concepts like the unique features of OOPS, differences between Java and C++ etc. Read through basic algorithms they like to refer algorithms by their names. - Do not show in the interview that you are looking for working on cutting edge stuff etc. This goes for all I-Banking IT. Focus more on brand name etc., and possible client and business Interaction (seems they love it!)

Airtight Networks

 

Job Profile: Java Developer

One Line Advice: Be the best at what interests you !

Placement Process:
Technical Interview--> Technical Interview--> HR Interview

Round 1 - Technical Interview
Question 1: Core Java Interview Questions (Google it & You will Get thousands)
Question 2: Logic based questions for example calculation of offset in Pagination scenarios.

Experience: This round was basic elimination of people weak in their java basics and logic.

Round 2 - Technical Interview
Que 1: OS basics and application based questions
Que 2: Networking fundamentals
Que 3: Programming Logic Based questions
Que 4: Data structure and algorithms

Experience: Saying you're favorite subject/what you're good at means you have to be best at it.

Round 3 - HR Interview
Que: Questions may be many but they all want the same thing from you !

Experience: Most importantly you need to be sure what you have, what you want and what you think this position can give you.

How to face interview:
Work smart not hard and you will find a way which isn't as long as it seemed to be !
Keep your basics in place and logic intact.
Be clear in your thought process and confident in your approach.

EntcEngg: Hello Shantanu, welcome to EntcEngg and really thank you for giving your valuable time to us.

Shantanu: It's my pleasure to be part of this wonderful initiative from you !

EntcEngg: Tell us something about yourself, where have you done your engineering from and which branch?

Shantanu: I am a 4th year E&Tc Engg student from Pune Institute of Computer Technology.

EntcEngg: What was your aggregate for all the years and did you prepare for you exams keeping placements in mind?

Shantanu: My aggregate was 61%. No, I didn’t prepared for any exam.

EntcEngg: Did you have a company in your mind as a Dream company, you always wished to work with?

Shantanu: Yes I did !  I wanted to work with a startup or at least with similar environment organisation. So the only company which came in that category was Thoughtworks.

EntcEngg: When did you start taking placements seriously and how did you prepare for them?

Shantanu: Well frankly speaking, I didn't prepare for any aptitude exam. The company i got placed was seeking general apti preparations. So if you are good with the  basics like Logical reasoning , quantitative analysis and English grammar you have won half of the battle.

EntcEngg: What extra-curricular activities you did apart from studies?

Shantanu: I volunteered for various college’s technical events from 1st year of my Engg and i was a part of college’s Robocon Team in 3rd year.

EntcEngg: Tell us in brief about your placement, the number of rounds and type of questions?

Shantanu: I got placed at Accenture in the month of September this year. It was mass recruiter so the requirement for aptitude was general aptitude preparations as i mentioned in the above question. For Aptitude preparations, practice RS Aggarwal for quantitative, logical and verbal.

EntcEngg: Tell us about the Interview. What did they ask and how did you answer those questions?

Shantanu: The Interview was not that tricky. The recruiters were asking general information about me and the project.

Comparison between PIC and 8051

8051- if u want a cheap controller with basic functions then 8051 will suffice . It will be of great use in your low cost college projects.

PIC- Cheap , used in refrigerators and low budget projects .

8051 and PIC need multiple clock cycles per instruction. AVR and ARM execute most instructions in a single clock cycle.

8051 and PIC have limited stack space - limited to 128 bytes for the 8051, and as little as 8 words or less for PIC. Writing a C compiler for these architectures must have been challenging, and compiler choice is limited.

Real Time Applications and Projects of PIC

1) PIC can be used to design Data Acquisition System

2)Digital clock can be implemented using PIC

3)Frequency counter are another application

4)PIC can be used as Timers, counters

5)We can design a calculator using PIC

How To Configure and Run DSP Processor

Digital signal processor (DSP)

Digital signal processor (DSP) is a special type of microprocessor (or a SIP block), with its architecture optimized for the operational needs of digital signal processing.


Digital Signal Processors (DSP) take real-world signals like voice, audio, video, temperature, pressure, or position that have been digitized and then mathematically manipulate them. A DSP is designed for performing mathematical functions like "add", "subtract", "multiply" and "divide" very quickly.

C6713DSK in CCSv5

What is inside a DSP processor?

A DSP contains these key components:

• Data Memory: Stores the information to be processed by processor
• Program Memory: Stores the programs which the DSP will use to process data
• Input/Output: Serves a range of functions to connect to the outside world
• Compute Engine:It performs the math processing, accessing the program from the Program Memory and data from  Data Memory
