🔥 DWDM Engineer Interview Question — Find the Node Position using Python Script!
This is one of the most common and basic questions asked in automation interviews. Whether you are applying at Amazon, Ciena, Nokia, Huawei, Tejas Networks, or any telecom company — if the role requires automation, they will test your scripting knowledge.
In this video, I will show you:
✅ How to find a node's position from a list of network nodes
✅ How to write a simple Python script step by step
✅ How to explain your code to the interviewer
✅ Why position starts from 0 and how to fix it
✅ Testing the script with multiple nodes — Delhi, Chennai, Kolkata
This is perfect for DWDM Engineers, NOC Engineers, NMS Testers, and anyone preparing for telecom automation interviews.
📌 Code used in this video:
nodes = ["delhi","mumbai","channai","kolkata"]
position = 0
for node in nodes:
if node == "channai":
print("Node found at position:",position +1)
position = position +1
Output: Node found at position: 3
