Texas Instruments Interview Process

I applied at Texas Instruments for the post of Software Engineer through a staffing agency. The process took one week and I was interviewed at Texas Instruments. There were a total of four rounds in the hiring process at Texas Instruments.

Round 1 - Telephonic Interview
The first thing in the process was the telephonic screening or interview. The round lasted for about an hour. It began with a formal introduction from both sides and then I was asked in detail about my background and studies. After all that stuff, there were some human resources based questions which I was prepared for. A few technical questions were asked after that but all basic. After that, my face to face interviews were scheduled.

Round 2 - First Face to Face Interview
Most probably, you will have to answer all the questions you answered in the previous round and thus please don't lose your patience. Just be calm and keep answering whatever is being asked. Once all the basic information about you is grasped by the interviewer, you will be then asked some details about your family background as well. There was nothing technical asked in this round.

Round 3 - Second Face to Face Interview
This round of interview was totally technical. However, what surprised me was that a couple of aptitude based questions were asked too and believe me they were tough. Other than that, there were questions regarding designing and algorithm. The interviewer would want to weigh your skills but other than that, you should be willing to solve or answer anything asked. What matters most is how much efforts you put even if you don't know the answer. Some of the technical questions that were asked:
Q1. Differentiate between Singly Linked List and Doubly Linked List data structures.
Q2. Algorithms based problems.

Round 4 - HR Interview
The HR interview was the nicest of all. Probably I'm saying this because the person who took my interview was really nice and nicest of all. Most of the questions were resume based and I had no problem answering them. A few aptitude problems were asked too. Then, there were some expected HR questions.

How to crack Texas Instruments Interview

Cracking Texas Instruments interview should not be a difficult job. I'm saying this because, two of the interviews including a telephonic interview were just a basic introduction and nothing else. I was hoping for more of the technical stuff but you will be asked that in just one round. To prepare for that round, make sure you go through data structures and algorithms. Of course be in practice with your aptitude solving skills. You may be asked two or more of them. The HR interview is pretty relaxing and you can expect all the usual questions along with resume based questions. So prepare for that.

Rest, I can only wish you best luck during the interviews. It's not hard, just prepare a bit and you will be able to crack it.

Thanks Anmol for sharing the details of your interview.

Tricky Iq Question

In a jar, there are some orange candies and some strawberry candies. You pick up two candies at a time randomly. If the two candies are of same flavor, you throw them away and put a strawberry candy inside. If they are of opposite flavors, you throw them away and put an orange candy inside.

In such manner, you will be reducing the candies in the jar one at a time and will eventually be left with only one candy in the jar.

If you are told about the respective number of orange and strawberry candies at the outset, will it be feasible for you to predict the flavor of the final remaining candy ?
