Q1. Basic questions on antenna parameters.
Add your answer
Q2. Design aspects of Antenna array.
Ans. 
Antenna array design involves elements such as element spacing, beamforming techniques, and array geometry.
• Element spacing determines the directivity and beamwidth of the array.

• Beamforming techniques like phase shifting and amplitude tapering help steer the beam in a desired direction.

• Array geometry, such as linear, planar, or conformal arrays, affects the radiation pattern and polarization.

• Antenna array design also co...read more

Q2. How will you get the tilt in the base station antenna?
Ans. 
The tilt in the base station antenna can be adjusted by physically changing the angle of the antenna.
• Tilt can be adjusted by loosening the bolts on the antenna mount and manually changing the angle of the antenna

• Specialized tools like tilt meters can be used to ensure the correct angle is achieved

• Remote electrical tilt (RET) systems can also be used to adjust the tilt of the antenna electronically

Questions were really simple, no big topics like dynamic programming or graphs were asked.
My questions -
Q.1 Find the second largest number in an array. (Started from brute force, went to maps)
Q.2 Reverse a number.

Then some OPS questions and some SQL questions.

Similar as the one before.
Q.1 Find Second largest number. (Idk why they asked it again)
Q.2 Question related to string (I think it was find if its a palindrome string or not)

Then some questions regarding my stack, (mobile development), the work i did, questions regarding deployment of apps, security and app lifecycle.
