Bosch Coding Questions 2025-2026 | Placement Interview Problems with Solutions

Bosch’s coding round assesses programming and DSA for software and embedded roles. The online test or technical interview typically has 1–2 coding problems (easy to medium) plus aptitude and technical MCQs. They look for correct logic, clean code, and basic data structures (arrays, strings, stacks). Focus on fundamentals and time-bound practice to match the exam pattern.

Bosch Coding Round at a Glance

Format: OA with coding + aptitude + technical MCQs, or technical interview with coding. Difficulty: Easy to medium. Topics: Arrays, strings, basic DSA, OOP. Focus: Correctness, clarity, and fundamentals.

Arrays & Strings

1. Two Sum

def two_sum(nums, target):
    seen = {}
    for i, num in enumerate(nums):
        if target - num in seen:
            return [seen[target - num], i]
        seen[num] = i
    return []

2. Valid Parentheses

def is_valid(s):
    stack = []
    mapping = {')': '(', '}': '{', ']': '['}
    for char in s:
        if char in mapping:
            top = stack.pop() if stack else '#'
            if mapping[char] != top:
                return False
        else:
            stack.append(char)
    return not stack

3. Reverse String

def reverse_string(s):
    return s[::-1]

4. Palindrome Check

def is_palindrome(s):
    s = ''.join(c.lower() for c in s if c.isalnum())
    return s == s[::-1]

5. Merge Intervals

def merge(intervals):
    intervals.sort(key=lambda x: x[0])
    merged = []
    for interval in intervals:
        if not merged or merged[-1][1] < interval[0]:
            merged.append(interval)
        else:
            merged[-1][1] = max(merged[-1][1], interval[1])
    return merged

6. Maximum Subarray

def max_subarray(nums):
    max_sum = current_sum = nums[0]
    for num in nums[1:]:
        current_sum = max(num, current_sum + num)
        max_sum = max(max_sum, current_sum)
    return max_sum

7. LRU Cache

from collections import OrderedDict

class LRUCache:
    def __init__(self, capacity):
        self.cache = OrderedDict()
        self.capacity = capacity

    def get(self, key):
        if key not in self.cache:
            return -1
        self.cache.move_to_end(key)
        return self.cache[key]

    def put(self, key, value):
        if key in self.cache:
            self.cache.move_to_end(key)
        self.cache[key] = value
        if len(self.cache) > self.capacity:
            self.cache.popitem(last=False)

Company-Specific Focus Areas

Bosch often emphasizes arrays and strings (traversal, validation, simple algorithms), stacks (e.g. parentheses, expression evaluation), basic OOP and programming logic, and efficiency (correct time complexity). Embedded/automotive roles may see problem statements that lean on logic and implementation rather than advanced DS. Practice aptitude and technical MCQs alongside coding.
