Lattice Semiconductor (india)

First Online assesment was there which we gave from college, consisted of aptitute and 2 dsa question difficulty was moderate to hard then technical interview was there interview was easy to moderate

Technical Interview 1 : How to reduce the ML Model Size ? Explain the process of Quantization,Knowledge Distlliation & prunning What is difference between Quantized aware Training and post training quantization ? Why Prunning is most effective in Tree Based Models ? Have you done any project Relevant to Training Machine learning Models on edge Devices ? Do you worked with Raspberry pi/ ESP 32 / Arduino ? What is Yolov8 , its applications and types ? what are efficient ways/tools to prepare and annotate dataset for yolov8 ? what is non maximum supression in yolov8 ? How does compilers work ? What is the difference between static and dynamic Linking ? what are different formats in which ML Models can be saved ? what is CNN ? what different type of preprocessing do you do in CNN? what is normalization ? Technical Interview 2 : What are Heaps ? How heaps are used for memory allocation & Management ? what is difference between python and java ? what is python virtual machine ? what is difference between list and tuple ? what is a linked list ? write a code to reverse a linked list. what is logistic regression ? explain bell shaped curve in logistic regression Explain bias vs variance tradeoff in context of machine learning what are pointers in C ? what is difference between structures and union in c ? Based on Resume : Explain your project.. what is the size of dataset, what processing you do and which models you applied ? what is accuracy of your regression Model ? what are AR,MA,ARMA AND ARIMA ? why you choose fb prophet for time series forecasting over traditional LSTM ? How to develop a full stack Machine learning Website ? give flow HR : Do you any plans for Future Education or MS ? what is your overall interviews experience ? what is your permanant address ? How you tackle challeges in a team ? what are your hobbies ? where do you stay in Pune ? VERDICT : SELECTED

Conducted pen paper test of based on core concepts of basic electronics then technical interview and HR round. Interview was mostly around Resume and Tools and technologies used. Interview experience was good.

Asked Questions Related to Digital Electronics and VLSI development flow. Basics of Digital Electronics are must and familiarity with VLSI design tools and flow is must. Good interview experience. Also one project using Verilog is must. Asked questions related to the project and Questions of Verilog programming.

6 Rounds a long day interviewe based on the expertise written on resume, Basic on the DSP, Embedded system, FPGA, Data Structure + discussion about Individual projects involved + HR final
