Pre-Interview Gestures

Student X :

In this Technical Interview round, the interviewrs asks questions related to softwares and your projects. They may ask you to write a code. All you have to do is to keep calm and must prepared for questions from your specific branch.

Student Y :

The interviewers are mostly interested in knowing that what new ideas you have which will be helpful or beneficial for the company or, any new coding techniques which are your own.

Apart from this, questions will be asked related to your coding branch. They may ask anything related to your Projects too. 


  • Difference between Zigbee and Bluetooth.

Ans: 1. Zigbee aims at automation whereas Bluetooth aims at connectivity of mobile devices in close proximity.
2. Zigbee uses low data rates, low power consumption on small packet devices while blue tooth uses higher data rates, higher power consumption on large packet devices.
3. Zigbee networks support longer range devices and more in number compared to Bluetooth networks whose range is small.

  • Drawbacks of android

Ans:  1. Not all the apps available in the store are compatible with the different levels or ranges of Android phones.

2. The phone’s efficiency is bound to take a hit as multiple programs run simultaneously in the background at any given time.

  • For 1:2:4 ratios the weight of cement is 50 kg then how many kg are the weight of sand and aggregate?

Ans:  It is the ratio of cement:fine aggregate (i.e.sand) :coarse aggregate.

So , for the ratio 1:2:4.

If you take 50 kg of cement,


2*50 = 100kg of sand.


4*50 = 200kg of coarse aggregate

  • What is object oriented programming?

Ans: Object-oriented programming (OOP) is a programming language model organized around objects rather than “actions” and data rather than logic. Historically, a program has been viewed as a logical procedure that takes input data, processes it, and produces output data.

  • What is mean by TCP?

Ans: TCP/IP stands for Transmission Control Protocol/Internet Protocol, which is a set of networking protocols that allows two or more computers to communicate. The Defense Data Network, part of the Department of Defense, developed TCP/IP, and it has been widely adopted as a networking standard.

  • Do you know which body sets standards for Wireless communication?

Ans: 802.11e — a wireless draft standard that defines the Quality of Service (QoS) support for LANs, and is an enhancement to the 802.11a and 802.11b wireless LAN (WLAN) specifications. 802.11g — applies to wireless LANs and is used for transmission over short distances at up to 54-Mbps in the 2.4 GHz bands.

  • Tell me the advantages of baseband modulation over broadband?

Ans: Whereas baseband uses digital signaling, broadband uses analog signals in the form of optical or electromagnetic waves over multiple transmission frequencies. For signals to be both sent and received, the transmission media must be split into two channels

  • Which modulation do we use in Wi-Fi?

Ans: WiFi systems use two primary radio transmission techniques. 802.11b (<=11 Mbps) − The 802.11b radio link uses a direct sequence spread spectrum technique called complementary coded keying (CCK). The bit stream is processed with a special coding and then modulated using Quadrature Phase Shift Keying (QPSK).

  • What are the IEEE standards for Wi-Fi?

Ans: IEEE 802.11 is part of the IEEE 802 set of LAN protocols, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) Wi-Fi computer communication in various frequencies, including but not limited to 2.4, 5, and 60 GHz frequency bands.

  • What are the functions of network layer?

Ans: The primary function of the network layer is to permit different networks to be interconnected. It does this by forwarding packets to networkrouters, which rely on algorithms to determine the best paths for the data to travel. These paths are known as virtual circuits.

Post Interview Gestures

Student X :

At the end I was asked if I am having any queries regarding the company. As being silent shows them that I am either nervous or not interested in the job. So, I asked questions related to welfares Reliance Jio does and about my field I will be working on. 

After this, they said me to wait for the results and call next candidate.
